No, the M3 has the same launcher as the M2. Only difference, is the M3 carries more missiles in storage (no need for dismounts, so more room for ammo).

It makes sense for the U.S. to send its surplus Dragons and early-model TOWs before sending Tank-Breaker (Javelin) but I can see the U.S. sending the the latest ATGMs as China appears to be at the breaking point- "the enemy of my enemy is my friend" and all that.

There is precedent both ways- holding back and providing the top of the line. In a time of emergent world war, I can see the U.S. sending current gen gear- maybe not big ticket items like the M1A1 or top-of-the-line F-16 models (hence the LAV-75 shipments). But an ATGM that could thin out the most modern Soviet MBTs? Hells yeah!

In WWII, Lend Lease saw the Soviets (never on very good terms with the Western Allies) receiving both crap M3 Lees (the Russians called them "Graves for Seven Brothers") and Valentines and the same current M4 Shermans being used by U.S. and Commonwealth armored divisions c. '43-'44.

The v1 chronology mentions the US sending the Assault Breaker system, which would have been state-of-the-art, even in a 1995 that saw continued high levels of defense spending from 1986 onward.

To give a better idea of how state-of-the-art and devastating the Assault Breaker is, the Assault Breaker program eventually produced the CBU-97 SFW bomb.

http://www.globalsecurity.org/milita...ons/cbu-97.htm

It's probably the most devastating antiarmor weapon ever devised. You drop a CBU-97 over an armored brigade, and it pretty much ceases to exist.

This is OT for this thread, but this is one of those weapon programs that would make the Soviets say, "Oh shit! We better invade now before they come up with something worse!"

[Targan]

So Paul, what do you say to say to one or more variants of the LAV-75 that tried using an ATGM launcher or two to increase the vehicle's anti armor capability instead of the 105mm conversion. I'm not saying they would have ever been as numerous as the M20 Ridgway/LAV-75 105mm conversions (I love your work on those) but there might be a few ATGM-equipped LAV-75s in the US or China (or both) that were being used for evaluation before the "missile drought" made the 105mm conversion the better option.

Would you be prepared to consider doing a write up for a couple of LAV-75 ATGM conversions Paul?

[Legbreaker]

China has some very good missiles at their disposal - HJ-8, HJ-9, HJ-13 and HJ-73/AT-3. I'd be more inclined to see the original LAV-75 fitted out with launchers for them, or simply replace damaged turrents with missile, rocket and recoilless weapons.

I can do that; what missiles do you want me to use?

The Dragon can actually be easily added to existing LAV-75s if they have a commander's machinegun. There is a rare, little-known mount replacement that allows a Dragon to be mounted in place of a commander's machinegun on tanks that have a US-compatible commander's machinegun mount. I've never seen one in the flesh, but we were told about it during gunnery class and it's in the TMs.

Scratch that; the Stryker MGS turret we used on the LAV-75A4 will not allow the use of that Dragon mount; due to the installation (it is actually about 3 feet ahead of the commander in a mount integral to the turret).

Note that the M2HB is at right angles to the Dragon. It obviously does not require replacing the machinegun....

Right out of the manual!

[pmulcahy11b]

As for missile armament for the LAV-75A4 (or I guess A5) -- I've been doing some thinking. Canon does say that the US sent Tank Breakers to China; that makes Javelins a possibility. A less sensitive alternative would be the TOW II system. And since it is vehicle-mounted, a heavier missile like the Hellfire is (to me) the best choice.

Or we could go nuts and arm it with the Hypervelocity Missile.

[Raellus]

TOW or Hellfire would probably require some sort of box mounting but could be fired from the safety of inside the vehicle. This would add to the weight, bulk, and maybe profile of the LAV.

The other option is an external Dragon or Tank Breaker mount for the commander like the one posted by Leg. I like this a bit better. The gun/missile combo makes the M20 particularly versatile. Add a 7.62mm coax and an M2 for the commander and the Ridgway will be able to take on almost all comers.

I'm not sure but I think Targan may be thinking about a version armed only with ATGMs, kind of the like the M901/M113 ITV. If this is the case, bigger is better and I would go with Hellfire. The v1.0 U.S. Army Vehicle Guide presents a similar concept with Hellfires mounted on a Bradley chasis (the M920 Hellfire AT vehicle on p.33). The Hellfires are exposed, though, and I would guess that would eventually lead to system degredation due to exposure to the elements and such.

On the other hand, such a vehicle wished-for by Targan already exists in canon. On page 32, there's the M917 ADATS vehicle based on the LAV-75 chasis. To my understanding, the ADATS system was intended for both SAM and AT capabilities. IIRC the ADATS system was never adopted but I kind of like it in the T2K universe. I say go with that. Targan, what do you think?

Targan, what do you think?

I'm aware of the ADATS vehicle (one turned up in my campaign, ex-Canadian vehicle somehow obtained by the 78th ID in New Jersey). That's not what I was suggesting. I had in mind original pattern LAV-75 variants with some sort of ATGM launcher added to it, either of the type that is bolted on and fired electronically from within the vehicle or of the type that is fired from a hatch.

We've already talked about how early in the Sino-Soviet War the experience of the Chinese original pattern LAV-75s in combat led to the US creating the M-20 Ridgway with a 105mm turret because the basic LAV-75 was found lacking when in combat with Soviet MBTs right? Well what I'm suggesting is that they might well have trialled a number of different variant options, not only the LAV-75A4/M20 Ridgway with the 105mm gun, but also basic LAV-75s with box-type ATGM launchers, LAV-75s with hatch fired ATGM launchers, heck maybe even a few US-only M20 Ridgway evaluation vehicles with ATGMs added too.

Sorry. I misunderstood. Not trying to read into what you wrote.

I think some sort of universal hatch mount along the lines of what Leg posted that could accept either the Dragon, the Tank-breaker/Javelin, or similar model ATGM (the Soviets made one- I can't recall its exact NATO designation right now- that was configured almost exactly like the Dragon) already used by the PRC would be the simplest option. Maybe the initial batches of LAV-75 were sent with Dragons, then later, when things started going really badly for the Chinese, the U.S. acquiesced and sent the newer Tank-breaker/Javelin either before or with (or both) the upgunned LAV-75A4. The ADATS-armed LAV-75 would fill the requirement for an exclusively missile armed version.

[ChalkLine]

Really, if you send LAV-75s with ATGMs you don't need to upgun the ARES turret.

(By the way, the ARES turret is really modular. There's lot of images of it mounted on Stingray, M551 and even M8 chassis)

Here's a site with many images, although it's a wacky group associated with the infamous 'M113 'Gavin' Sparks'

[StainlessSteelCynic]

Targan, did you mean the M113 based ADATS? Because I think Raellus was refering to the 1st edition US vehicle guide where it has the LAV75 based version. GDW made stats for two fictional versions, anti-tank and anti-aircraft gun.

I agree with all that.

True. That is sort of what started me down this line of thinking. If the reason for creating variants of the original LAV-75 was that the 75mm gun wasn't killing Soviet MBTs it stands to reason that fitting an ATGM to the LAV-75 might be the simplest way to give it tank-killing capabilities. But when the missile drought kicks in the 105mm variant would become the better option. That still means that at some point there probably would have been a number of variants being trialled if not fielded, including both the 105mm variant and also one or even several LAV-75+ATGM launcher variants. See where I'm coming from? I'm not saying anything we've come up with so far is deficient.

Actually you are correct, the one that turned up in my campaign was the M-113 version (that was actually used by the Canadian Army IRL, although I've never checked to see if it is still in service with them). But I was aware of the fictional ADATS vehicle depicted in the US Vehicles Guide. In my campaign that LAV-75 chasis ADATS vehicle would only have been fielded by the US Army in very limited numbers, the M-113 version used by the Canadians would have been far more numerous.

I agree with this. The 34 ADATS in Canada are mounted on the M113. They are still in use but were going to be modified to a Canadian LAVIII and modernized. This is no longer the case and in any regards wouldn't have fit into the timeframe anyways... so M113 it is.

With surplus M113s (replaced) it seems probably to mount something like this rather than build a completely new model.

[Legbreaker]

My thoughts are that the 105mm armed LAV would not have been sent to China as by the time it was developed, that conflict was effectively won and lost.
HOWEVER, it's certainly conceivable that a number of LAV-75 were modified in country to fit missile launchers, either in a box such as the Bradley, or rail mount such as BMP. The Dragon (or Chinese version) mount would be another relatively common modification.

By the time the M-20 was ready for production the US army would be in need of all of them (with a few maybe going to the marines). This is not to say a few prototype M-20s weren't sent to China for testing, but I'd think they would be very few and far between.

Hmm, According to the "Authorised Levels of Principal Combat Vehicles & Weapons" on pages 17-20 of the 1st ed US Army Vehicle Guide, 392 LAV-75s were required to fit out units with the vehicle assigned to them. I would estimate an actual production run of around 450 would have been desired to provide training vehicles and a few replacements.

If production was commenced early enough (mid to late 80's) virtually the entire order may have been produced before the war. Perhaps the 105mm was already on the drawing board when the Soviet/China war broke out and so those vehicles sent to China were already several years old and due for upgrading anyway?

If however the production run was delayed until a year or two before hostilities, production is likely to have been much less, with a substantial proportion rolling out of the factories and directly onto ships bound for China.

Of course we've nothing in canon I can see that states any LAVs were sent, so it might well be that US units went to war with the LAV-75 and upgraded peicemeal in the field....

Further reading of the US vehicle guide reveals a total of 68 LAV-75s still operational (or at least on the books). Some of these vehicles are in the hands of units never offically assigned them (such as the 8th ID). Obviously there may also be a few in enemy hands, or not "on the books" for any number of reasons.

[Webstral]

Production of the LAV-75 or its variants almost certainly would have continued right through the nuclear exchange and for as long as possible thereafter.

C'mon Web, give us your reasons

Cadillac Gage has most of its production facilities along the Gulf Coast of the US, though some major ones are also found in Southern California, and some major sub-assemblies were made in the Far East. (HQ is Slidell, Louisiana; I've been there and it's basically a "big little town). In 1994, Cadillac Gage merged with Textron.

I'm not sure if the 1994 merger would have taken place in the T2K timeline. Cadillac Gage had a lot of slumping sales for its products, especially its armored vehicles -- yet continued to pour mountains of money into R&D and prototype vehicles and products (those technicians and scientists, as well as its research database, is what made Cadillac Gage attractive to Textron). In 1993, Forbes called Cadillac Gage the fifth worst performing major company in the world.

However, in a T2K timeline, Cadillac Gage might have seen its sales go up stating around 1991 or so, and way up starting in 1994 or so. So it may have been able to continue on as its own entity. A lot of countries would have been in the market for inexpensive armor that was still decent in quality. The US may also have been looking for a company to make less expensive vehicles to supply to allies in sort of a Lend-Lease program.

Had the merger with Textron taken place, however, they may have also had some of Textron's facilities to work with. They are headquartered in Providence, Rhode Island, and have manufacturing facilities all over the US, as well as in several other countries (again, with a lot in the Far East). Textron also has under its umbrella AAI, Bell Aerospace, Cessna, and Lycoming Engines, as well as some smaller non-defense related companies. That's a lot to work with -- there's something to be said for decentralization of facilities.

In either company's case, there could be quite a bit of surviving and possibly operational facilities in T2K. Cadillac Gage's vehicles were also known for their simplicity of manufacture and maintenance, and it could be "outsourced" to other places relatively easily compared to other companies' products.

I don't know if that's what you meant, Web, but I thought it would be good info.

[Legbreaker]

My thoughts are that in both timelines (1st and 2nd ed), Cadillac Gage would very likely have remained an independant company. The spectre of war just on the horizon would likely have boosted their sales and possibly even allowed a little expansion.

This would probably have gone against them once the nukes came down, as they wouldn't have easy access to the Textron facilities. Mind you, nobody is likely to have easy access to anything that's not within walking distance....

The will to produce might be there, and I'm not just talking about the M-20, but production across the board - vehicles, ammo, weapons, food, clothing, energy, comsumer goods, you name it. But, once transportation and energy networks went down (about ten seconds after the nukes), the ability to produce would virtually disappear.

Some production of low tech items might still be possible on a relatively small scale, but production of high tech electronics, etc required for the fire control systems would be nigh impossible. The best that could be hoped for is using the last few spare parts that avoided EMP to cobble together a few more units.

Once the nukes fell, the technicians, engineers, mechanics, and so forth would be more interested in personal survival than collecting their paycheck, no matter how patriotic they were, no matter there was a global war raging with US troops fighting in Europe, Korea, the middle east, and Alaska (and probably a few more minor locations).

In early 1997 it appears fighting was more widespread than even at the height of WWII! It only grew from there...

So, to me the will may have been there to produce, at least at the command level, but on the ground where the work is actually done, next to nothing would have been possible.

I just put Paul's excellent write-up of the M-20 Ridgway to good use and wanted to give him kudos again. I have been thinking about Thunder Empire in the car lately, which led me to realize I couldn't remember what crew size had been determined. I was able to see that Paul recorded a crew size of two with justification. Thanks, Paul.

Appreciate the kudos. You know, I had to go back and find that one; I don't remember doing it!

[Grendel]

Hello all, this is my first post to this forum and I found it by doing a search for the HSTVL. I played T2K as a teenager in the 80's when it first came out. After highschool I joined the USARMY as an 11B I gave up role palaying games. I still have all of the original and some of the second run books and use them as reference for my oldest hobby of building 35th scale armor models. I grew tired of building "real" vehicles and now base all of my builds on the T2K universe. I have been a member of the International Plastic Modelers society for over 25 yrs. I have two club members, Former Gunnery Sgt Wade Bolin (USMC) and MSgt Micheal Reed, who were tank testers at Aberdeen in the late 70's, the 80's, early 90's and had the privealage of working on the HSTVL and the RDF light tank. Below I will post two excerps from Janes Light Tanks regarding both vehicles. I was very glad that GDW included the LAV-75 in the T2K universe.

The HSTVL was never intended to enter production and was used as a test bed vehicle for technology that would later find it's way onto the M1A1/A2 and the Korean K1A1. According to both Mr Bolin and Mr Reed the Ares 75mm Hyper Velocity autocannon was a far superior weapon to the M68/M68A1 105mm gun. Mr Bolin often describes the Ares weapon as being able to lay 3 rounds down range in a 6in circle on a moving target. Mr. Reed describes testing the weapon on the M48/60 Patton series as well as T-55, T-62 and T-72 tanks aquired from Isreal who "aquired them from Syria. He says that he fired a single APFSDS round from the Ares gun into the front plate (which is always the thickest part of a MBT) of a Polish manufactured T-55 and it penetrated to the engine. The ARES cannon was never adopted for use because of the expense of the weapon not becuase of its killing capability. I see no reason to upgun the LAV-75 especially to what both gentleman refer to as an "inferior" weapon. You could always upgun it to the ARES 90mm Hyper Velocity auto cannon that was being developed along side the 75mm version. This would give the LAV-90 the capability to engage the T64, ERA equiped T-72 and T-80 tanks as well as the T-90 which turns out to be little more than an improved T-72.

The HSTVL was not based on the M113 though it did share automotive components. It actually had the tracks, roadwheels, idler wheel and drive wheel of the M551 Sherdian. The HSTVL was mounted with several different turrets and engines. The RDF light tank has the drive sprocket, tracks, and idler wheel of the Bradley and roadwheels of the M113.

I hope the two articles I post below will give you fine gentleman a better insight to the LAV-75's realworld counter part. I also hope to soon post some photos of my 35th scale T2K based vehicle models and dioramas. I am very pleased to find the game still played and enjoyed all these years later.

Here u go.

High Survivability Test Vehicle (Lightweight)

Development
The High Survivability Test Vehicle – Lightweight (HSTV-L) was developed under the direction of the TACOM project manager for Armored Combat Vehicle Technology at the US Army Tank-Automotive Command, Warren, Michigan.
Following the field testing, the HSTV(L) is being used for experiments in fire-control and stabilisation. Stabilisation processing has been converted from analogue to digital. Various stabilization control algorithms are being tried along with different combinations of transducers to determine effects on gun pointing performance and the possibility of eliminating some of the expensive sensors such as gyros. The TACOM Motion Base Simulator, a huge shaker table, is being used to provide terrain input. These tests began in September 1982 and are to continue for a year or more.

Description
The high survivability of this vehicle is derived from the low silhouette, high horsepower per ton, duplication of sights, improved night vision capabilities, and the lack of specific driver and gunner controls. Any crewman can shoot and both hull crewmen can drive.
Although a test vehicle, the HSTV(L) is not a variable parameter test bed but an exercise in system realism for the three-man crew, hunter/killer fire control concept and low silhouette.
Armament for the HSTV(L) consists of a 7.62 mm M240 machine gun for both commander and coaxial position and a 75 mm smooth bore cannon. The cannon employs a revolving breech and telescoping ammunition which enables the automatic loader to load one round per 11/2 seconds. The in battery-firing recoil mechanism has a fixed piston that allows the greater mass of recoil cylinder and breech mechanism parts to recoil during firing. The 75 mm gun and automatic ammunition feeder are designed and made by ARES Inc, Port Clinton, Ohio.
Texas Instruments supplies the fire-control system which uses the hunter/killer concept. The commander uses a stabilised hunter sight that revolves independently of the turret. Once a target is selected on this sight, the turret and killer sight can be aligned with it. The gunner can then destroy the selected target while the commander returns to search with his hunter sight. Both direct vision and FLIR (Forward Looking Infra-red) optics are available for either sight. The commander can use either a binocular direct view optic eyepiece for improved clarity and reduced power drain, or a video screen. In the hull, a video screen visible to both gunner and driver receives transmissions from hunter and killer sights.
The electronic fire control processor uses inputs from the sights, crosswind sensor, muzzle reference, vertical reference system, and an eye-safe CO2 laser rangefinder to compute proper gun pointing. The laser rangefinder is supplied by Raytheon. Automatic tracking and rate aid tracking can also be accomplished by the fire control processor.
Both elevation and azimuth stabilisation is provided for the 75 mm gun with a slaved killer sight and an indepen¬dently stabilised hunter sight. Fire-on-the-move capabilities are improved by decoupling the yaw motion of the hull from the turret. Cadillac Gage supplies the gun control and stabilisation system for HSTV(L).
Propulsion for the HSTV(L) comes from a gas turbine engine mounted beside the transmission with a cross-drive gearbox connecting the two. Avco Lycoming supplies the nonregenerative 650 horsepower modified helicopter gas turbine. The transmission is an X-300 Detroit Diesel Allison automatic four-speed with lock-up torque converter. Auxili¬ary power is provided by two 250 amp generators and a 60 gpm hydraulic pump. The hydraulic pump supplies power for the engine compartment mounted oil cooler fan and through a hydraulic slip ring; it also supplies power to the gun control system and automatic ammunition loader in the turret.
Teledyne supply the fixed height hydro-pneumatic sus¬pension system. A 355.6 mm jounce and 127 mm rebound travel is possible due to the small 558.8 mm diameter road wheels. The track is an improved version of the type found on the M551 Sheridan.
The man-machine interface for the HSTV(L) is of prime importance. The use of the hunter/killer concept allows both the gunner and the commander to contribute as much information as possible towards the neutralisation of the enemy. The use of pressure sensitive isometric rate controller thumb switches allows for more precise gun control while firing on the move. The driver and gunner seating positions are semi-reclined for maximum comfort in a minimum space. The tv screens considerably improve fire-on-the-move sighting clarity.

Rapid Deployment Force Light Tank (RDF/LT)

Development
The Rapid Deployment Force Light Tank (RDF/LT) has been designed as a private venture by AAI Corporation which has already built the prototype of the High Survivability Test Vehicle (Lightweight) under contract to the United States Army Tank-Automotive Command.
The prototype was shown for the first time in October 1980 when it was said by the company that it could be in service by 1984, if a decision on production was taken in the immediate future.
The vehicle is airportable: the Lockheed C-5B transport aircraft can carry eight RDF/LTs, the C-130 and C-141 could each carry two and the Navy/Marine Corps CH-53E helicopter can carry one slung under its fuselage.
This vehicle, with some changes and improvements in armour protection, is AAl’s entry in the MPGS competition.

Description
The hull of the RDF/LT is made of all-welded aluminium armour with the driver sitting at the front of the hull on the left and the commander/gunner to his right. Both crew members have a single-piece hatch cover that opens outwards and has three integrated periscopes. Between the driver and commander/gunner, in the upper part of the glacis plate, is the hull-mounted auxiliary sight.
The main armament consists of a 75 mm ARES cannon mounted in the centre of the hull behind the crew. The 75 mm ARES cannon is fed from an automatic magazine holding 60 rounds of APFSDS and multi-purpose ammunition and when used for indirect fire has a maximum range of 12 000 metres. To the right of the main armament there is a coaxial 7.62 mm machine gun.
Mounted above and behind the main armament is the stabilised rotary head which is the primary sight. The main armament is fully stabilised and the fire-control system includes a digital computer. The fire-control system is similar to that of the HSTV(L) and is fully described in that entry.
The engine and transmission are mounted at the rear of the hull and the complete powerpack is on extensible rails to facilitate maintenance in the field.
The torsion bar suspension consists of five dual rubbertyred road wheels with a drive sprocket at the rear, idler at the front and one return roller.
Appliqué steel armour can be fitted to the RDF/LT for increased protection. As an alternative to the 75 mm ARES cannon which is mounted in an unmanned turret and fitted to the prototype vehicle, an AAI Universal One-Man Turret which is also armed with a 75 mm ARES cannon, fed from an automatic loader, can be fitted.

Variants
In 1982 AAI announced a new version of this vehicle fitted with a new one-man turret also armed with the ARES 75 mm automatic cannon. This has a single-piece hatch cover opening to the rear, six periscopes for all round observation and forward and to the right of the hatch is a stabilised sight for target acquisition/firing.

Grendal, this is a tremendous addition to our knowledge base of the LAV-75. It's exciting to know that the initial combat experience of the LAV-75 might have been very positive, whether that would have been in China in 1995 or Europe/Korea in 1996.

Absolutely Outstanding Grendel, thanks for the post, I think it will give everyone a good perspective on the LAV75 - might even have to adjust a few things in our minds as to how good or bad it might have actually been.

Amazing amount of information there Grendal. Thanks very much.

Very cool info.

I can't see front line US/NATO AFVs being sent to China in 95-96 to bolster their war effort, due to the threat of technical intelligence being giftwrapped for Soviet forces capturing vehicles.

I could possibly see older AFVs, but suspect that the real fight changer for the Chinese would be if we could just dump Javelin CLUs and missiles (Tankbreaker, whatever) by the boat load. Training Chinese troops to use an M1/LAV-75/M60 or whatever else can take some time, especially because it's not just the crews fighting the vehicles it's the maintainers and mechanics, the logistics guys who have to learn what widgets need to be front loaded due to frequent breakage and on and on.

Worst case you send them some seriously game changing piece of kit that they end up just abandoning because they can't maintain it or resupply it (apparently a lot of German troops ended up doing this with StG-44s -- get handed this super assault rifle without any programmed ammo resupply scheduled so after a few days in the line you're back to a Mauser bolt gun or something . . . ).

Javelins, though, would be kind of like the Afghan Stingers if you were facing a conventional Soviet armored attack. Getting the Chinese Stingers probably wouldn't hurt either -- both can be taught to somebody with zero formal education at all (for which: see previous reference to Stingers in Afghanistan) and both can be learned fast. Soviet units pushing up against Chinese infantry formations where the squad level anti-tank weapon just changed from an RPG-7 to a Javelin launcher would be deep into the realm of rude surprises.
