On a cold wet Sunday afternoon I was leafing through a relatively recent copy of Jane's AW Warships when I came across the Armada Nacional of Paraguay
They lack a sea coast but still have a navy which must be the joy to the taxpayers.......
4 main ships
"Paraguay" Commisioned May 1931
"Itaipu" commisioned April 1985
"Teniente Farina" commisioned July 1939
"Captain Cabral" commisioned 1908 - noted as "in excellent condition and took part in an exercise in 2010 - she must be the oldest warship in the world (not counting USS "Constitution")
Interestingly the "Paraguay" totes 4 x 120mm guns - thus outgunning a T45 Destroyer (1 x 114mm gun) in the surface-surface mode
I presume they have a Strategic Review every thirty years or so........
