The 5-inch Forward Firing Aircraft Rocket or FFAR was an American rocket developed during World War II for attack from airplanes against ground and ship targets. ==Operational history== The first FFARs were developed by the U.S. Navy and introduced in June 1943. They had a 3.5-inch diameter and a non-explosive warhead, since they were used as an aircraft-launched ASW (Anti-Submarine Warfare) rocket and worked by puncturing the hull. It was accurate enough for use against surface ships and land targets, but these missions required an explosive warhead.〔Parsch 2004〕 A 5-inch anti-aircraft shell was attached to the 3.5-inch rocket motor, creating the 5-Inch FFAR, which entered service in December 1943. Performance was limited because of the increased weight, limiting speed to 780 km/h (485 mph).〔Parsch 2006〕 The High Velocity Aircraft Rocket, or HVAR, was developed to fix this flaw.〔 A list of aircraft that used FFAR: * Douglas SBD Dauntless - dive bomber * Vought F4U Corsair - carrier based fighter 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「5-Inch Forward Firing Aircraft Rocket」の詳細全文を読む スポンサード リンク
