The Influence of History

Note the "62" on this image from the Navy.mil announcement - has sanity finally returned to USN hull numbers? With the recently announced selection of the Fincantieri offering for the United States Navy's (USN) FFG(X) program, we now have enough knowledge of what the future USS Constellation will look like to post a notional missile loadout page. Now, the Constellation-class remains very much a paper design and will not join the fleet until at least 2026, so this post is even more speculative than my other missile loadouts posts . However, the result of the FFG(X) program has several unique aspects to its armament that are worth discussing. We now know that the planned armament of the Constellation-class will consist of a 32-cell Mk 41 Vertical Launch System (VLS) forward, four quad canister launchers for the RGM-184 Naval Strike Missile (NSM) amidships, and a 21-cell box launcher for RIM-116 Rolling Airframe Missile (RAM) aft. This is a considerable quantity and v...

The Spruance -class destroyers have probably the most complex missile loadout history of any non-air defense ship. Unfortunately, the numerous changes and variation have surprisingly little available documentation and I have been forced to rely heavily on photographs to fill in the gaps. Therefore, many of the dates in this post are only estimates. The Spruance -class was designed during the late 1960’s as a modern warship to replace the large number of WWII-era Fletcher , Allen M Sumner , and Gearing -class class destroyers that were swiftly becoming obsolete. Force structure analysis during the design process revealed that while air defense systems significantly increased unit cost, it was ASW that drove force size requirements. Therefore, it was decided to supplement DDG and DLG production with a more affordable DD design that eventually became the Spruance -class. In a drive for greater efficiency, the DD would also share its hull with a DDG design. While the related DDG was neve...

During the 1970's, several new technologies such as the helicopter, the gas turbine, and the lightweight surface to air missile became available, driving the creation of a new generation of warship. The United States led the way with the Spruance -class destroyers, and the British followed with the Type 22 frigates. In Japan, these developments took somewhat longer, but eventually led to the creation of the new type of general purpose destroyer. Hatsuyuki-class The first of these new ships was the twelve members of the Hatsuyuki -class, which entered service beginning in 1982. Unlike the preceding Japanese destroyers that relied on guns, Hatsuyuki was built with a substantial missile battery for countering air, surface, and subsurface threats. This consisting of an octuplet ASROC box launcher forward, two quadruple Harpoon canister launchers amidships, and an octuplet Sea Sparrow box launcher aft (on the first ships five ships this was the American Mk 29, while the later ships we...
