HH 3E Jolly Green Giant 2026. Sikorsky HH 3E Jolly Green Giant helicopter model. The Sikorsky CH 3E was the USAF version of the Sikorsky S 61 amphibious transport helicopter developed for the U. S. Navy. The USAF initially operated six Navy HSS 2 (SH 3A) versions of the S 61 in 1962, eventually designating them CH 3A Bs. They were so successful the USAF ordered 75, modified as CH 3Cs, featuring a new rear fuselage design with a ramp for vehicles and other cargo. The first CH 3C was flown on June 17, 1963. When 41 CH 3Cs were updated with more powerful engines in 1966, they were redesignated as CH 3Es. Forty five more were newly manufactured. Later, 50 CH 3Es were modified for combat rescue missions with armor, defensive armament, self sealing fuel tanks, a rescue hoist, and in flight refueling capability. They were redesignated HH 3Es and used extensively in Vietnam under the nickname "Jolly Green Giant." Mahogany Wood. Scale: 1 48. Rotorspan 14 1 2 inches, Length 18 1 2 inches.
