Aries Got her Gun (back)
We’ve always been fans of the six-pack of Pegasus-class hydrofoil patrol missile (PHM) boats that entered service in 1977, were sadly underutilized during the Cold War, and were retired wholesale when it ended.
Each carried eight Harpoons, a 76mm/62c MK75 OTO Melara Super Rapid forward, and a GE LM2500 gas turbine that could drive the whole enterprise at 48 knots.
These 133-foot “Boeing boats” were magic to behold.
The plan was that the Navy was to build over 30 of these little boats to operate in a couple of forward-deployed squadrons, with Italy, Germany, and possibly Japan to follow, but as soon as PHM champion Elmo Zumwalt left the CNO’s office, that plan went right out the window and just six were completed– although Japan and Italy did build some even smaller (75-foot) Sparviero/1-go boats, still with the Otobreda 76 forward but with half as many missiles.
Sent out to the scrappers in 1993, only one survives: ex-USS Aries (PHM-5), preserved as a memorial on the Gasconade River in Missouri.
The Aries PHM museum was stripped of almost everything that made her such a fetching design, but recently got a distinctive MK 92 FCS “egg” dome to go back on her pilothouse and, finally, a deactivated MK 75 mount.
The Ordnance Shop at the U.S. Coast Guard Yard, which inherited the MK75 program from the Navy in 2015 when the last FFG-7 retired, recently released a precious OTO mount, #135, to Aries.
No. 135 is unique, as its gun house had been ported and windows installed so that it could be used as a training aid at Coast Guard Training Center Yorktown, but with the service getting rid of the last of its MK75s as the old 270-foot Famous (Bear) class cutters go through a SLEP and get a smaller (MK38) mount, it wasn’t needed anymore and, incredibly, it is the same early OTO-made mount (not FMC) that came from Aries in 1993.
“We are delighted to know that the gun itself was original to the USS Aries,” noted the museum. “After all these years, they have been reunited due to the efforts of the Coast Guard Ordnance Yard in Baltimore, MD. We are so grateful for the contributions of all involved.”
Bravo Zulu, folks.
Now to get her some surplus Harpoon cans —maybe off a laid-up Tico before they are all sunk or scrapped.
