A firearm that fires a bullet using gunpowder from a barrel with a caliber of 20 mm or more. It is also called a field gun or field artillery. Until World War II, it was used as the main source of firepower, and many types of guns were used, including cannons, howitzers, mortars, mortars, tank guns, anti-tank guns, anti-aircraft guns, and machine guns. After World War II, high-performance firearms such as precision-guided missiles and rocket artillery were developed, and large-caliber guns disappeared. Currently, guns are generally classified based on the ballistic shape of the bullet, and are classified into guns, howitzers, mortars, anti-aircraft guns, and recoilless rifles.

口径20ミリ以上の砲身で火薬を使用して弾丸を発射する火器。野戦砲または野砲ともいう。第二次世界大戦までは火力の主力として使用され、加農砲(カノン砲)、榴弾砲(りゅうだんほう)、臼砲(きゅうほう)、迫撃砲、戦車砲、対戦車砲、高射砲、機関砲など数多くの砲種が使用されてきた。第二次世界大戦後には精密誘導ミサイルやロケット砲といった高性能な火器が発達して大口径の火砲は姿を消している。現在、火砲は弾丸の弾道形状を基本として分類されることが一般的であり、加農砲(gun)、榴弾砲(howitzer)、迫撃砲(mortar)、高射砲(anti-aircraft)および無反動砲(recoilless rifle)に分類される。 [村井友秀] [参照項目] | | | |陸上自衛隊の榴弾砲。全長11.3m、全幅3.2m、全高4.3m、全備重量40.0t、速度49.6km/h。155mm榴弾砲、12.7mm重機関銃M2©Shogakukan"> 99式自走155mm榴弾砲 陸上自衛隊の自走砲。全長7.99m、全幅3.18m、全高4.4m、全備重量約38t、速度約53km/h。35mm高射機関砲×2©Shogakukan"> 87式自走高射機関砲 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
