In World War II virtually every major category of warship (except for mine warfare) changed roles from the intended role leading into the war, to the utilized role by the end of the war. The most well known example is how the Aircraft Carrier and Battleship swapped roles. Prior to the war the aircraft carrier was intended to perform a scouting, support, and defensive role for the fleet to enable the Battleships to engage the enemy fleet, however by the end of the war the Aircraft carrier was the primary offensive platform against both land and sea targets.
The Battleship, originally intended to be the major offensive strike platform from sea, leveraged new technologies like radar to become a primary early warning vessel (a scouting role) for the fleet, and also transitioned into a supporting role for amphibious operations, while also becoming the primary AAW warship for the carrier fleets. While it is easy to be distracted by the big guns of the Iowa class, it was her killbox capability in AAW defense that made the ship a devastating platform by the end of the war.
What is less well known is how the roles of other combatants changed as well. Heavy Cruisers were originally designed to be scouts for the fleet, but by the end of the war the Heavy Cruiser had hardly done any scouting in any engagement of the war, rather had performed virtually every other role. The light cruiser was intended to be a destroyer leader, but by the end of the war was a primary AAW escort for aircraft carriers. Destroyers were originally designed to defend the van and rear of the battle line against torpedo attacks by other destroyers, but by the end of the war they were primarily a AAW and ASW defensive platform. Even submarines, intended to provide forward reconnaissance and an early strike platform against enemy warships were ultimately given the task to destroy merchant ships and disrupt enemy lines of communication.
One would think the Navy had learned the lessons of WWII, but there are a number of examples since WWII where a ship designed for a certain role in war has ultimately been used for an entirely different purpose.
We have previously described the
example of the Oliver Hazard Perry class. Originally intended to be a convoy escort platform never intended to operate independently in a war zone, the ship class went on to do exactly that. In
No Higher Honor by Bradley Peniston, the book does a masterful job outlining the decision making process behind the intended role of the Perry class frigates, and the role ultimately provided during the Tanker Wars.
Another modern example is the Spruance class destroyer. Originally designed to be the primary ASW defensive platform for the fleet, the combat record of the class tells a completely different story.

In October of 1987 the USS Leftwich (DD-984) and USS John Young (DD-973) participated with the guided missile destroyers USS Hoel (DDG-13) and USS Kidd (DDG-993) in
Operation Nimble Archer. Both Sprunace class destroyers, despite the lack of adequate AAW defenses, sailed at night through the Strait of Hormuz to attack a pair of Iranian oil platforms. Using their 5" guns, the combined force put thousands of shells on both platforms before special forces were sent over to gather intelligence and destroy the platforms. After the attack, the destroyers returned the following night back through the Strait of Hormuz.
In 1991 and 1999 the Spruance class was also utilized in the Gulf War and Kosovo conflict respectively. Rather than defend against enemy submarines, as originally intended, the Spruance class was instead utilized as a
launch vehicle for Tomahawk cruise missiles against enemy defenses. Throughout the entire career of the warship class, despite being designed and deployed specifically for ASW, the ship never engaged and sank a single submarine. There are numerous other examples. In
1966 the USS Tortuga LSD (26), a ship designed for Marine amphibious operations, was positioned at the mouth of the Co Chien River to support Navy riverine and coastal interdiction operations in operation Game Warden. The Burke class AAW destroyer has never shot down an aircraft, while the USS Kitty Hawk (CV 63) was used as a Sea Base to support Army, Marine, and SOF forces into Afghanistan following 9/11.
We note that in every case, the design which did not attempt to overemphasize a specific ship characteristic allowed these ships to be flexible and support some other role during the lifetime of the class. That is particularly true with surface combatants, even the limited multi-mission weapon payload ultimately allowed for independent operations, while the extra space of the Spruance class allowed it to ultimately support cruise missiles. The Arleigh Burke class today is being adapted to shoot down ballistic missiles, a role never envisioned when the class was originally built.
We are observing other examples today. Amphibious ships are designed and built solely for the purpose of amphibious warfare, which ironically is the least likely role these ship will be utilized for in their lifetime. Observing the last 6 deployments of an L class ship not related to a scheduled Expeditionary Strike Group deployment, five of the six ships deployed were done so for reasons in the service of the Navy rather than the Marine Corp, and if you go back further than the last half dozen deployments this trend holds true.
The Pearl Harbor (LSD 52)
Partnership of the Americas deployment, the USS Fort McHenry (LSD 43)
African Partnership Initiative deployment, the USS Carter Hall (LSD 50)
5th Fleet deployment (PDF), the current USS Whidbey Island (LSD 41)
5th Fleet deployment, and the USS Harpers Ferry (LSD 49) deployment for
CARAT have all been amphibious ship deployments in support of Navy operations, not specifically Marine operations. The only exception we have observed was the USS Wasp (LHD 1) deployment to
ferry MV-22s to Iraq.
In other words, the we have observed the last 5 independent deployments by LSDs have been primarily for the purposes of providing a naval mission. The LSD, an amphibious ship with the major design characteristic being its rather large well deck or rather large cargo deck, depending upon class, is in fact becoming a major asset for the surface Navy utilized in a role never intended during the design of the platform.
We offer this observation for consideration because this week we intend to spend extra time discussing expeditionary warfare strategies. JROC will be getting together in February to discuss the MPF(F) composition, and because there are so many issues involved that are rarely discussed in the open source outside of large professional studies, we intend to discuss as many of the issues as possible.
After all, decisions at design time matter, but should never be made with the intention of perfection. It is with some irony we point out the last two incidents of the surface Navy employing their weapon systems are not Cruisers, Destroyers, or Frigates, rather the USS Carter Hall (LSD 50) against some skiffs off the coast of Somalia, and the USS Whidbey Island (LSD 41) firing some warning shots at a boat getting a bit too aggressive in the Straits of Hormuz. In both instances the ships were either positioned or positioning themselves for operations under the category of Sea Basing.
Why does that matter? Because the JROC should recognize today's surface Navy not only has active duty Captains with considerable modern day Sea Basing experience in the form of the afloat staging bases in the 5th fleet, but these Captains also have more real time combat experience at sea than most Captains in the Navy. We believe if JROC fails to utilize these officers as obvious resources for a discussion of modern Sea Basing it would be a tragedy of wisdom.
