Cold War US Navy Destroyers:
Gearing FRAM I
Sumner FRAM II
USS Sampson (DDG-10) underway in 1988
The Destroyers of the class Charles F. Adams succeeded the Forrest Sherman (1953), themselves still modeled on the Gearing of the Second World War. Built in large series (23 units, DDG-2 to DDG-24, the USS Waddell, DDG-24, was launched in February 1962 and accepted in service in 1964.), they retained typical characteristics such as the continuous deck hull, the side bulwarks, two chimneys, but they innovated considerably by being the first to implement a weaponry of missiles. The center of the system was the new MAA Tartar (SAM-1) replacing the 127 mm DP turret. This system included a double launcher and a drum below equipped with 40 vectors. This missile, operational in 1962 and dependent on a very specific radar guidance system, had a range of 50 km and a mach speed of 1.8. The second system was ASROC, which was promised a good career, both in the US Navy where it equipped all the escort ships and abroad, and included an eightfold launcher placed in the center with a reload of 8 vectors. The missile, with a range of 9 km, a safety distance from the danger of torpedoing by an opposing submarine, carried an ASM charge (tactical head of 10kt) or an acoustic torpedo with a load of 45 kgs.
The Charles F. Adams, classed as “fleet escorts”, a term that highlighted the primacy of the aircraft carrier over the rest of the fleet, had been a technical feat because although they were 6 meters or more One meter wide that the Forrest Sherman, and with the same 70,000 hp propulsion unit, managed to keep their speed of 33 knots thanks to a reduced load weight. This was made possible by a lighter construction and a much longer hull, guaranteeing excellent hydrodynamic penetration. The qualities of these buildings were recognized and both the FRG and Australia built replicas. However, their light construction and narrow partitioning left little room for extensive extensive work, and in fact they were only superficially modernized (improvements in electronics, including the JPTDS computerized tactical management system, CMEs. 32 and multi-purpose fire control Mk.86). Their Tartar Mk11 / 13 launchers were set up in the 1980s to receive the Harpoon and were fitted as the last linker of the SPS40 and 52 radars. They were removed from active service between 1989 and 1992. In 1990, there were still 21 in activity. Three were sold to Greece in 1992. They are still in use. Another was transferred to Australia to serve as a spare parts bank.
