Pig Safari
Some 40 years ago this month, September 1985: “A Marine aboard the battleship USS Iowa (BB 61), armed with an M60 machine gun, participate in a self-defense force test during Exercise Ocean Safari ’85.”
Note the stern 16″/50 triple gun turret in the foggy Atlantic background and the battleship’s new Douglas fir deck which replaced her WWII-era teak. PH1 Jeff Hilton. 330-CFD-DN-ST-86-02496
Note the Woodland M81 pattern camo, and new PASGT kevlar frag vest (but not a K-pot, still rocking the WWII-era M1 steel helmet). The M60 appears to be a Vietnam standard “Pig” model. Around this time the Corps was replacing these heavy guns with the pared-down M60E3 which shaved a few pounds and, post-Desert Storm, would ultimately move (slowly) to the FN Mag 58 M240G variant in the 1990s.
As for Marine Dets on battleships and carriers, they went the way of the M60 in 1998.
For reference, the MarDet on Iowa in 1942 was 110 men, and by 1985 had shrunk to just 58.
Their jobs in the 1980s were primarily to man the ship’s eight M2 .50 cal mounts as well as the 27-member crew for Mount 55– their dedicated 5″/38 Mk 28 twin turret– spearhead the ship’s reaction force, as well as provide a guard for the skipper and admiral (if aboard) and protect any “special weapons” that may or may not have ever been carried by the battleships.
