Brazil needs new anti-submarine helicopters to accompany its “AH-11” Super Lynx models, and replace HS-1 Squadron’s aged SH-3A/B Sea Kings. HS-1 bases out of Sao Pedro da Adelia near Rio, and generally serves aboard Brazil’s sole aircraft carrier, NAe Sao Paulo (ex-Foch).
Brazil is standardizing on Eurocopter’s EC725 Cougar as its medium helicopter across all 3 services, but that model doesn’t have a naval/ anti-submarine variant. Brazil could have chosen a comparably-sized naval helicopter like the EH101 Merlin, or the forthcoming NH90 NFH. Instead, they opted for Sikorsky’s smaller S-70B/H-60 Seahawk. It’s in wide service around the globe, and offers commonalities with the Brazilian Army’s fleet of S-70/UH-60L Pave Hawk search and rescue aircraft. Now, the final pieces of Brazil’s contract and support structure are falling into place.
