Task: Question Answering
Input (English): Passage: Battleship -- The value of the battleship has been questioned, even during their heyday. There were few of the decisive fleet battles that battleship proponents expected, and used to justify the vast resources spent on building battlefleets. Even in spite of their huge firepower and protection, battleships were increasingly vulnerable to much smaller and relatively inexpensive weapons: initially the torpedo and the naval mine, and later aircraft and the guided missile. The growing range of naval engagements led to the aircraft carrier replacing the battleship as the leading capital ship during World War II, with the last battleship to be launched being HMS Vanguard in 1944. Four battleships were retained by the United States Navy until the end of the Cold War for fire support purposes and were last used in combat during the Gulf War in 1991. The last battleships were stricken from the U.S. Naval Vessel Register in the 2000s. Today, with the exception of Russian Kirov-class battlecruiser, aircraft carriers are the only types of capital ships in service.
