Brian's mock-up picture is before Army UTTAS flight testing revealed the prototype UH-60A inflight vibration levels were well above specification. At that time, the Boeing UTTAS candidate did meet the vibration spec. Subsequently Sikorsky added an extension to the main rotor mast to raise the main rotor and thus reduce airframe vibrations. That move was successful, and Sikorsky ultimately won the competition. As a point of interest, my Navy LAMPS MKIII source selection vote was for the Boeing candidate, but others prevailed. The following year, Mike Coumatis flew a prototype Black Hawk and landed on a Navy frigate to demonstrate the need to move the tail wheel forward. I flew the first Seahawk flight with a factory test pilot in February 1979, and subsequently Dick Childers and I flew all the initial Seahawk Flying Quality and Performance (FQ&P) test flights, and RAST workups. I served as the NATC LAMPS MKIII Program Manager from June 1977 until my HSL-32 squadron command tour in Feb 1981. I piloted the first Navy flight and was the first NATOPS qualified pilot of the SH-60B Seahawk, am listed in Jane’s Who’s Who in Aviation and Aerospace: U.S. Edition and is a member of The Society of Experimental Test Pilots. Dick Childers continued the RAST testing, and Larrie Cable and his team performed most of the LAMPS MKIII systems testing. Following my command tour, I was assigned as the Deputy LAMPS MKIII PM in PMA-266 at NAVAIR. At the time, LAMPS MKIII and the F-18 were the only major Navy acquisition programs to not suffer any aircraft losses during developmental flight testing.

I reached out to the Sikorsky archives and they sent me back what they had. I included the attachment for reference, but according to the martial Sikorsky provided: “A full-scale mock-up of Sikorsky Aircraft's proposed U.S. Navy LAMPS Light Airborne Multi-Purpose System) helicopter was unveiled May 13 at the opening of the American Helicopter Society's annual three-day forum at the Sheraton Park Hotel in Washington, Following the forum, the mock-up was taken on a tour of three key naval installations It was exhibited at the Naval Air Test Center. Patuxent River, Md. on May 20; at the Norfolk Va. Naval Air Station on May 28 and 29, and will visit the Naval Air Development Center Warminster. Pa on June 5.” Sikorsky said they actually didn’t have a photo of it themselves. I recommend reading the entire article rom 1975 they sent (attached) if you are interested in the beginning of the Navy H-60 program. I also learned today the museum where I volunteer is getting an SH-60B. Brian
