Warhead data
I have a plan to add many other man portable anti armor weapon systems.
For the life of me I can't figure out what formula they came up with to figure armor penetration and e-factor. The LAW and the RPG-7 seem equivalent until you get to damage. The stats for an RPG-7 are twice as effect as a LAW except both are class D anti-armor weapons. Need more Soviet Bloc weapons to for survivors of air landed forces and troops from Cuba. Anyway. Anyone know what the formula was for a rockets stats?

I came up with a formula that works. I compared it to the one that Kevin developed and it is bang on.
Explosive DPW Formula ((Explosive weight in kg / 0.563) x 1300) x RE RE (Relative Effectiveness) Values for Explosive Fillers PETN: 1.25 RDX: 1.22 Nitroglycerin: 1.12 Composition B: 1.01 Composition A4: 1.01 Composition C4: 1.00 Torpex: 0.94 Tetryl: 0.94 Tetrytol 75/25: 0.90 Amatol 80/20: 0.88 Pentolite: 0.88 Tritonal: 0.83 TNT: 0.75 Explosive D: 0.74 Picric Acid: 0.70 M1 Dynamite: 0.69 Guncotton: 0.69 Dynamite (60%): 0.62 Nitrostarch: 0.60 Gelignite (60%): 0.57 Dynamite (40%): 0.49 Black Powder: 0.41 Mercury Fulminate: 0.38 Ammonium Nitrate: 0.31 Gelignite (40%): 0.31 Lead Azide: 0.29 To convert real world explosive RE values, times it by 0.75 to come up with The Morrow Project ones.

From page 38 3d edition.
The only case in which the E-factor formula is not used is in the case of armor penetrating (shape charged) explosive warheads. In the case of these weapons the E-factor is found by determining how much armor the weapon penetrates. The Armor class of the weapons penetration is taken as that weapons E- factor.

Range 1000m Burst Radius 5m Type of Fire Single shot disposable Rate of Fire Single Feed Device n/a Feed Device Wt. n/a Basic Load 1 Load Wt. 2.37 kg Total Wt. Additional Comments: A lightweight, disposable, rocket launcher firing a high explosive warhead. The warheads will penetrate 28 centimeters of steel. The “back blast” from the weapon prevents it from being fired from inside a room smaller than 5x5 meters. Found in Load out: #1, 9, Attachment 1594 Attachment 1595 RPD-7D Anti-Tank Launcher E-Factor: 1030 Weight (Empty): 6.8kg Minimum Range: 30m Effective Range: 300m Max. Range: 920m Type of Fire: Single Shot Burst Radius: 5m Round Weight: 2.3kg Anti-Armor Class: D Basic Load: 2 rounds Additional Comments: The RPD-7D is the standard anti-tank launcher of the Warsaw Pact Forces, although it was beingsuperseded by newer designs like the RPD and RPG-18 by the time the War broke out. The basic design is quite simple and effective, though the round can be pushed off-target by strong crosswinds. This particular version can be disassembled into two parts to shorten the launch tube for the convenience of paratroops. The RPG-7V is a recoilless, shoulder-fired, muzzle-loaded, reloadable, antitank grenade launcher. It fires a variety of rocket-assisted grenades from a 40-mm smoothbore launcher tube. It is the standard squad antitank weapon in use by the OPFOR. The RPG-7V is light enough to be carried and fired by one person. However, an assistant grenadier normally deploys to the left of the gunner to protect him from small arms fire. The RPG-7V requires a well-trained gunner to estimate ranges and lead distances for moving targets. Crosswinds as low as 7 miles per hour can complicate the gunner's estimate and reduce first-round hit probability to 50% at ranges beyond 180 meters.

There's the two light Anti Armor weapons.
Thanks Nuke11 by the way. As you can see the Writers worked up the E-factor for the RPG-7 for "Final Watch". Anybody know by what formula as the normal one would not apply for a shape charged weapon. Next any Idea how they came up with the DPW for the manufactured weapons like the LAW. Its not like the manufacturer was handing out the recipe. Thanks in advance!

There isn't a simple formula. The curve for steel using the table on p.38 is not continuous (plot it in Excel and see). Only wood has a linear relation between thickness and armor value. As an approximation for steel: For each x10 in thickness, x20 armor value. For each x2 in thickness, x2.5 armor value. The M72 LAW has a penetration of 28cm or 11". This gives you an E-factor of about 1100 (1185). AV 48 = 2.54cm (1") steel. 11" is 11x thicker or ~3.5 doublings. Final AV = 48 * (2.5^3.5) or about 1185. Quote:
A small simplification: DPW = 2309 x RE x explosive mass, kg (1300/0.563 = 2309) For DPW 533, I get about 270g of RDX (using 0.85 value in TM1-1) which fits pretty well with the M72 rocket.

 Name: SD-44 Towed AT Gun Airborne Variant with Aux Propulsion unit. Cal. 85mm E-Factor : See by type below. Wt. (Empty) 3.1 Metric Tons Min. Range 50m Eff. Range 1500m Max. Range Burst Radius by type Type of Fire Rate of Fire 8 RPM with a trained crew / 15 rpm burst for indirect fire. Feed Device Manual Feed Device Wt. n/a Basic Load 21 mixed type Load Wt. by type Total Wt. Additional Comments: Description The 85 mm auxiliary-propelled field gun SD-44 was designed by the F F Petrov design bureau. It is basically the 85 mm Divisional Gun D-44 fitted with an auxiliary propulsion unit: an M-72 two-cylinder petrol engine which develops 14 hp and gives a maximum road speed of 25 km/h. Fuel is carried in one of the trails. The engine is mounted on the left trail and ready use ammunition is carried in the right one. The engine provides power to the two rubber-tyred carriage wheels via a drive shaft and a differential. The conventional steering wheel and steering column are attached to a castor just behind the spades. The lunette is retained enabling the weapon to be towed if required, maximum towing speed is 60 km/h. A two-part folded rammer is mounted vertically on either side of the front of the shield. An infra-red night vision device can be fitted if required. The SD-44 has sometimes been incorrectly called the D-48.

Armor value 48 = 2.54cm of Rolled Homogenous Steel. (RHA)
2.54cm = 25.4mm Penetration for 85mm HVAP-T is 180mm. 180 divided by 25.4 = 7.086614473 Rounded to 7.087 inches of RHA 7.087 divided by 2.54 = 2.79000558 Rounded to 2.80 doublings from 2.54 AV 48 * (2.54^2.80) = 652.7932332 Rounded to 653. Efactor for HVAP-T is 653. Somebody please fact check that as I am unsure. Thanks!

Armor value 48 = 2.54cm of Rolled Homogenous Steel. (RHA)
2.54cm = 25.4mm Penetration for 85mm HEAT-FS is 300mm. 300 divided by 25.4 = 11.81102362 Rounded to 11.811 inches of RHA 11.811 divided by 2.54 = 4.6500093 Rounded to 4.65 doublings from 2.54 AV 48 * (2.54^4.65) = 3661.997299 Rounded to 3662 Efactor for HEAT-FS is 3662. Nope. Can't be right. I am screwing up the math in figuring how many times a penentration has doubled from the original 2.54 cm. Last edited by ArmySGT.; 06-07-2012 at 04:14 PM.

85mm HVAP-T
Armor Penetration (mm): 180mm (RHA) at 1,000 meters E-Factor = 113mm (RHA, 30°) at 500 meters E-Factor = AV 48 = 25.4mm RHA. For each x2 in armor thickness, x2.5 AV 180mm = 2.82 doublings. E-factor = 48 * (2.5^2.82) = 636 113mm = 2.15 doublings. E-factor = 48 * (2.5^2.15) = 344 HEAT-FS 300mm = 3.56 doublings. E-factor = 48 * (2.5^3.56) = 1253 AP-HE 90mm = 1.82 doublings. E-factor = 48 * (2.5^1.82) = 254 Another way of looking at: "For each x2 in armor thickness, x2.5 AV" is Armor thickness varies with 2^(a) Final armor value = 48*(2.5^(a)) So 180/25.4 is about 7.09, which is 2^(2.82). Using the scientific calculator in Windows: - Take the log of 7.09 (~0.851) - Store in memory - Take the log of 2 (~0.301) - divide by what's in memory - take the reciprocal (1/x) (~2.82) - use this answer to find AV/E-factor (48*[2.5^2.82]) It's roundabout but accurate...

Sorry, I wasn't sure how active the forum is.
Should have checked back in sooner. Consolidating the previous math: E-factor/AV = 48 * 2.5^[3.322(log(mm RHA) - 1.4049)] 3.322 ~= 1/log(2) 1.4049 ~= log(25.4) Checking , the formula returns slightly different values thanks to rounding: 300mm = 1255 90mm = 255 113mm = 345 180mm = 639 sub 1% differences are OK, I think.

 Name:Russian 122-mm Towed Howitzer D-30A Cal. 122mm E-Factor : See by type below. Wt. (Empty) 3.2 Metric Tons Min. Range Varies by ammunition type Eff. Range Varies by ammunition type Max. Range Varies by ammunition type Burst Radius by type Varies by ammunition type Type of Fire Rate of Fire 8 rpm burst / 6 rpm normal / 4 rpm sustained Feed Device Manual Feed Device Wt. n/a Basic Load 21 mixed type Load Wt. by type Total Wt. Additional Comments:The D-30A is a midlife product improvement of the D-30. The original D-30 was fielded in 1963 and the midlife product improvements occurred in the mid to late 1970’s. The original D-30 is in use with at least 50 different countries. The D-30, also known as the M1963, replaced the older 122-mm howitzer M-30 (M1938). The original D-30 was fielded in 1963 and the midlife product improvements occurred in the mid to late 1970�s. The original D-30 is in use with at least 50 different countries. The 2A18M D-30A and D-30M are midlife product improvements of the D-30 that are currently in production by the Gosudarstvennoe Unitarnoe Predpriatie Zavod 9 [Vysokodispersnye Metallicheskiye Poroshki AO]. The D-30 features a unique three-trail carriage, a conspicuous boxy shield for the recuperator above the tube, and a small protective shield between the wheels. The gun has a semiautomatic, vertically sliding, wedge-type breechblock. It is towed muzzle-first by a truck or armored tractor, at speeds up to 80 kilometers per hour, with its trails folded under the barrel. The D-30 can be recognized by its unique three-trail carriage, the conspicuous box-like shield for the recoil-recuperator mechanism mounted above the tube, the multi-baffle muzzle brake, and the small protective shield fitted between the wheels. Early models of the D-30 had a multi-baffle muzzle brake while the D-30M has a double-baffle muzzle brake. The gun has a semiautomatic, vertically-sliding, wedge-type breechblock. It can be towed by a truck (Ural-375 or ZIL-131) or armored tractor at speeds up to 80 krn/hr. It is towed muzzle-first by a large lunette just under the muzzle brake with its trails folded under the barrel. The D-30 is found in the howitzer battalion of BTR-equipped motorized rifle regiments and in the artillery regiment of motorized rifle, tank, and airborne divisions. A battalion of D-30s is also being added to some tank regiments as an interim measure. These D-30s will eventually be replaced by a battalion of 122-mm self-propelled howitzers 2S1. The maximum effective range of either howitzer is 15,300 meters. In firing position, the crew of eight unhitches the gun, lowers the central firing jack, raising the wheels high enough to clear the trail legs, and spreads the two outer trails 120� on each side. The revolving mount permits 360� traverse and is equipped for high and low angles of fire, making it fully suitable for antitank defense. It is doubtful that full elevation is possible when the breech is immediately over a trail leg. The D-30 can also be equipped with a IR or passive night vision sights for direct fire. The D-30 fires FRAG-HE and HEAT-FS variable-charge, case-type, separate-loading ammunition. The D-30 has a special nonrotating, fin-stabilized, HEAT projectile which allows it to effectively engage armored vehicles with direct fire. The HEAT round can penetrate up to 460 mm of armor at any range. Other types of projectiles include chemical, illuminating (S-462 weighing 22.4 kg), smoke (D-462 weighing 22.3 kg), leaflet, flechette, and incendiary. Recently an RAP has been introduced with a maximum range of 21900 m. There are at least two chemical projectiles for the D-30, with the CW agent is dispersed by the explosion of a TNT bursting charge. The Sarin projectile weighs 22.2 kg with 1.3 kg of Sarin agent. The 122 mm Lewisite projectile weighs 23.1 kg with 3.3 kg of viscous Lewisite agent.

     Name AT-3 Malyutka (SAGGER) Cal. E-Factor = A model 1835 / C model 2597 48 * 2.5^[3.322(log(400 or 520) - 1.4049)]= 2208.385244 Wt. (10.9 / 11.4 kg) missile, 30.5 kg launcher + guidance Eff. Range 500/500 Max. Range 3000/3000 Type of Fire Rate of Fire 1 Feed Device 1 per man pack case (two per AT team). BMD-1, 1 on rail + 3 stowed In each three-man team, the gunner carries a suitcase containing the control box, and two assistant gunners each carry one missile in a suitcase. Feed Device Wt. Basic Load - 1 guidance (gunner) + 2 launcher/missile case (assistants) Total Wt.30.5 kg launcher + guidance Additional Comments : AT-3 is classed by weight as portable (21-40 kg), rather than manportable (<21 kg). The launcher is also a missile carry case. The guidance panel can be located up to 15 meters from the launcher, and can control up to four launchers. If target is <1,000 meters from launcher, the operator can joystick the missile to target without using optics. Guidance elevation (°) is -5/ +10. Because the module is small and can be shifted, elevation and field of view are operationally unlimited. Improved versions can be used on older launchers, but in the MCLOS mode. The Slovenian Iskra TS-M thermal sight is available, with detection at 3,000 meters and recognition at 1,800 meters. Any AT-3 can be modernized to Malyutka-2 with replacement of warhead and or replacement of specific warhead and motor components. Last edited by ArmySGT.; 04-07-2014 at 09:37 PM.

  SYSTEM Alternative Designations: BAT (Battalion Antitank), and VARIANTS Date of Introduction: 1953 Proliferation: At least 50 countries Description: Crew: 4 vehicle with dismount, 2 vehicle mount, 8 dismounted infantry Caliber (mm): 106 Weight (kg): 130, 113 without the spotting rifle Length (m): 3.4, with a 2.85 m barrel Width (on M79 mount) (m): .8, 1.524 with the legs spread Height (on M79 mount) (m): 1.3 ARMAMENT Main Armament: 106-mm Recoilless rifle. Bore: Rifled 36 grooves, rh. The actual bore size is 105 mm; but is referred to as 106 mm to avoid confusion with the failed 105-mm M27 gun system. Breech Type: Interrupted thread , hand-operated Recoil System: Vented breech Feed: Manual Traverse (°): 360 Elevation (°) (M79 Mount): -17/+65 Rate of Fire (rd/min): 5 Emplacement/displacement time (min): INA Fire From Inside Building: No Complete Round Weight (kg): 13 Muzzle Velocity (m/s): 570 Spotting Rifle: .50 cal M-8C, magazine-fed. It uses a .50 cal semi-auto spotting rifle mounted along the axis of the barrel to determine proper elevation for the 106-mm rifle. The round matched to M40 round flight ballistics, and holds a 20-round magazine. SIGHTS Name: Bofors Modernization Package Daysight: Name: Simrad LP101 laser day sight (in place of the ranging gun) Others available: Computerized LASer Sight (CLASS) Upgraded systems may have the Simrad laser sight in lieu of the ranging (spotting) gun. Night Sights: Name: NVL-11 Mk IV II sight with computer LRF Range: 990 m. Others available: Simrad KN250 II sight, other II and thermal sights VARIANTS M40A1: Initial fielded version of the rifle which was commonly exported, with the M-8C spotting rifle. M40A2: Upgrade with an M79 mount. M40A4: The latest fielded version, with the M27 tripod. Other countries have produced the rifle, under license, and mounted it on various chassis. Bofors Retrofit Program: Upgrade program, with the Simrad sights and the 3A-HEAT-T round. The weapon can be porteed, carried on a vehicle pintel mount, then transferred to a ground semi-mobile tripod mount. M79 Mount: Tripod, ground, or vehicle M50 Ontos: Six-barrel mount on small tracked vehicle PAK-66: Austrian M40 on two-wheel carriage AMMUNITION Name: M344A1 Type: HEAT Range (m): Maximum Effective: 1,350 Maximum Range: 2,745 Armor Penetration (mm CE): INA E-factor = 1255 48 * 2.5^[3.322(log(300) - 1.4049)]= 1255.079738 DPW= 2332.149201 It uses 2.79lbs or 1 Kg of Comp B. Complete Round Weight (kg): 16.8 Muzzle Velocity (m/s): 503 Name: 3A-HEAT-T (Bofors upgrade) Type: HEAT-Tracer Maximum Effective Range (m): 2,000 Armor Penetration (mm CE): 700 + E-factor = 3847 48 * 2.5^[3.322(log(700) - 1.4049)]= 3846.98682 Complete Round Weight (kg): 14.5 Muzzle Velocity (m/s): 570 Name: M346A1 Type: HEP-T (HE plastic-tracer) Filler:7.72 lb (3.501733 KG) Comp A3 DPW= 8085.70675 Maximum Range (m): 6,870 Complete Round Weight (kg): 16.95 Muzzle Velocity (m/s): 498 Name: M581 Type: APERS-T (antipersonnel-tracer) (flechette) Fill (.5 g ea): 10,000 flechettes Maximum Effective Range (m): 300 Complete Round Weight (kg): 18.73 Muzzle Velocity (m/s): 438 Name: HEAP M-DN Type: HE antipersonnel (steel pellets) Fill: 1,000 steel pellets Maximum Effective Range (m): 1,500 Lethal Radius: 40 Complete Round Weight (kg): 16.4 Muzzle Velocity (m/s): 560 NOTES The producer of the LAHAT gun-launch ATGM (pg 6-58) offers to produce a version for use in the M40 launcher. The tandem ATGM is a viable threat to all modern armored vehicles. Use requires a tripod-mounted laser guidance unit, as used with MT-12 and 2A45M AT guns. The rifle produces a massive amount of noise and smoke which reveals its location. Thus a first round hit is critical. Last edited by ArmySGT.; 04-17-2014 at 02:03 PM.
