Question: What does seal stand for in the branch of the U.S. military that operates a list of destroyer classes as well as the USS Tarawa?

<P0-S0> this is a list of destroyer classes of the royal navy of the united kingdom, organised chronologically by entry into service. <SEP> <P1-S0> The United States Navy's ``Sea, Air, and Land ''Teams, commonly abbreviated as the Navy SEALs, are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. <P1-S1> Among the SEALs' main functions are conducting small - unit maritime military operations that originate from, and return to, a river, ocean, swamp, delta, or coastline. <P1-S2> The SEALs are trained to operate in all environments (Sea, Air, and Land) for which they are named. <SEP> <P2-S0> The first major warship produced by the U.S. Navy after World War II (and in the Cold War) were "frigates"—the ships were originally designated destroyer leaders but reclassified in 1975 as guided missile cruisers (except the became guided missile destroyers). <P2-S1> These grew out of the last all-gun destroyers of the 1950s. <P2-S2> In the middle 1970s the s entered service, optimized for anti-submarine warfare. <P2-S3> A special class of guided missile destroyers was produced for the Shah of Iran, but due to the Iranian Revolution these ships could not be delivered and were added to the U.S. Navy. <SEP> <P3-S0> boesch was born and raised in rochester, new york, and enlisted in the united states navy at age 17. he became a underwater demolition team (udt) frogman in 1951, serving on two udt teams. <P3-S1> he was chosen as one of the first seals, becoming chief of the boat of newly created seal team two in 1962. starting in 1968 and 1970, boesch completed two combat deployments during the vietnam war, where he earned the bronze star for heroic action. <P3-S2> during that time and later, boesch set physical and operational standards at seal team two. <P3-S3> in 1987, he became senior enlisted advisor for united states special operations command. <P3-S4> designated the "bullfrog", the longest-serving seal still on active duty, boesch achieved considerable renown within the force for his physical fitness training regimens and his military appearance. <P3-S5> after 45 years of continuous service, he retired from the navy in 1990 as a master chief petty officer. <SEP> <P4-S0> USS "Tarawa" (CV/CVA/CVS-40, AVT-12) was one of 24 s built during and shortly after World War II for the United States Navy. <P4-S1> The ship was the first US Navy ship to bear the name, and was named for the bloody 1943 Battle of Tarawa. <P4-S2> "Tarawa" was commissioned in December 1945, too late to serve in World War II. <P4-S3> After serving a short time in the Far East, she was decommissioned in 1949. <P4-S4> She was soon recommissioned after the Korean War began, serving in the Atlantic as a replacement for carriers sent to Korea. <P4-S5> In the early 1950s, she was redesignated an attack carrier (CVA) and then an antisubmarine warfare carrier (CVS). <P4-S6> Except for one tour in the Far East, she spent her entire second career operating in the Atlantic and Caribbean. <P4-S7> Consequently, "Tarawa" was the only ship of her class to never see combat action.
