Originally an anti-submarine warfare HSS-1. Converted to UH-34G and transferred to South Vietnamese Air Force in 1967. Later N586HS. 'RP' on the fuselage appears to be an individual aircraft code; 'DM' is painted on the nose.
This H-34 was retired to MASDC during March 1971 with the PCN/Inventory No. HD0150. Fortunatelly later she was rescued from a scrapyard near DM and transferred to the USS Midway Museum-Restoration Facility at North Island NAS. Currently she is on display on the flightdeck of this super museum.
This Seabat was delivered to the USN as a HSS-1 in March 1956. It served at some of its life with the Vietnam AF and after returning to the US was retired to MASDC as HD0025 during October, 1969. During the 1980s it was placed onto the civil registry as N583HS but is now part of the amazing collection at Bissell Auto & Body Co.
Wonderful Sikorsky helicopter, built in the 1960s. Unfortunately this strikingly-painted machine crashlanded during a heavy-lifting operation in Los Angeles on 13 March 2011 and sustained significant damage. Its current status is unclear.
This helicopter entered Marine service in 1961 serving in units around the US until retirement in 1970 and storage at MASDC. It is on display at the Udvar-Hazy Center as YP-13, a significant aircraft assigned to HMM-163 'Ridge Runners'. This combat unit operated in the Da Nang area of Vietnam and became one of the most decorated Marine helicopter squadrons of that war.
