"The Paraguayan Navy's Humaitá-class river gunboats may well be regarded as ancient by most modern standards, but their longevity pales into insignificance when compared to that Navy's Capitán Cabral (ex-Triunfo, ex-Adolfo Riquelme), which was first launched in 1907!... She was certainly still in service in 2016 ... one hundred and eleven years after she was launched!"
