This P-3C from VQ-1 was sent to AMARC 4 1/2 months after this photo was taken

This Sikorsky S-61N started life with British European Airways as G-ASNL and the fuselage was later shortened by Carson Helicopters in Perkasie, Penn. to increase its lift capacity. It was displayed at Heli-Expo 2008 inside the George R. Brown Convention Center and departed from a temporary heliport after the show. It is outfitted with an external water tank for fire fighting. It later flew overseas on behalf of the US State Department (as N220WW) until retired and sold to Croman Helicopters (re-registered N626CK) for use on heli-logging and firefighting contracts.

Pictured lifting off rw13R after a flying visit to BFI. Departed along with the two Aussie Wedgetails so presumably they were systems testing together.
