The Brazilian navy uses the S-70B Sea Hawk for anti-submarine and anti-surface warfare.

Displaying special colours to celebrate the 50th anniversary of HS-1, N-3035 is seen at its homebase.

N-3013 on the right hand side, is an AS-61D-3 that was delivered to the Marina do Brazil in 1984 and assigned to HS-1. Second to right is N-3030, a former US Navy SH-3D (BuNo 156490) that was delivered to Brazil in May'96, assigned to HS-1 and redesignated to SH-3B in Brazilian service. The third from the right is Sea King N-3018, also a former USN SH-3D (most probably ex BuNo 154107) which was also delivered in May'96 as SH-3B to HS-1. N-3018 is preserved in Rio de Janeiro, Espaço Cultural da Marinha since Aug'16. On the left N-3016 can be seen, see other picture on AirHistory.

N-3016 is an AS-61D-3 (SH-3A) which was delivered to the Marina do Brazil in 1984 and assigned to HS-1. The helicopter was withdrawn from service in October 2015.

Two SH-3As were based at the Sao Paulo during the very first carrier qualifications of the AF-1 Skyhawks. The helicopters were tasked to protect the carrier during its operations in the Atlantic Ocean.
