Seguí-class destroyer

The Seguí-class destroyer is a class of destroyers of the Argentine Navy. Five ships of the Allen M. Sumner-class destroyer were lent by the United States Navy and were in commission from 1972 until 1984.

Development
ARA Seguí was commissioned as USS Hank on 28 August 1944, ARA Hipólito Bouchard was commissioned as USS Borie (DD-704) on 21 September 1944 and ARA Piedra Buena was commissioned as USS Collett on 16 May 1944.

Seguí was the only one still in her Korean War configuration meanwhile, Bouchard and Piedra had FRAM configurations.

After World War II, they were in a mothball state, but on 1 July 1972 and 5 May 1977, they were handed over to Argentina based on the Argentina-US Ship Loan Agreement. All ships took on minor roles during the Falklands War. Bouchard and Piedra escorted the Belgrano in 1982 and were caught off guard by the submarine attack. They were dispatched to hunt for HMS Conqueror and made ASW grenade passes, but no contacts were made. Bouchard took a torpedo hit, the third Mk 8 torpedo launched on the Belgrano, but it failed to detonate.

USS Mansfield was also bought by the Argentina, but was never commissioned and used as spare parts for their current ships during that time.
