Screaming Helo got it right. JSHIP stands for Joint Shipboard Integration Project. I took part in two exercises , both out of NAS North Island, on board the USS Tarawa (see pics), & the USS Pelileu. We stayed on board the ship for a week off the coast of California, including some missions over to San Clemente Island so the SEALS & Ranger could play with each other.
I was a CH-47 flight engineer at the time with the Texas National Guard. All the aircrew members had to go through the Navy’s water survival course ( ie, the dunker course). I took the course at NAS Jacksonville. One of our IP completed a abbreviated LSO fam course. We then painted standard deck markings on one of the taxiways at our airfield & practice the technique of landing on a LPH. The first exercise had the CH-47’s from Dallas, UH-60’s from Austin & San Antonio, & AH-64s from Houston, so it was all Texas aircraft for the first trip I went on.
The second trip was more of the same, but with the addition of some active duty HH-60s from Moody, & OH-58D from Ft. Carson (one of which almost flipped over the deck due to rotor wash & a single tie down chain.
That was 1999 & 2000. World events have put an end to that training, & the new powers that be in Texas have called those trips “adventure training”.
