It consisted of a metal canister about in diameter filled with calcium hydride. It was launched by an ejector system colloquially referred to as ''Pillenwerfer'' (English: "pill thrower"). When mixed with seawater, the calcium hydride produced large quantities of hydrogen which bubbled out of the container, creating a false sonar target. A valve opened and closed, holding the device at a depth of about . The device lasted 20 to 25 minutes. The Royal Navy called it SBT (Submarine Bubble Target). ==See also== * Sieglinde (decoy) 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「Bold (decoy)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
