M29 81mm 迫撃砲

M29 81mm 迫撃砲(M29 81mm Mortar)は、アメリカ軍が使用していた迫撃砲である。

概要

第二次世界大戦および朝鮮戦争で使用されたM1 81mm 迫撃砲の後継として、1950年代後半に開発された。M29迫撃砲は、M1迫撃砲よりも軽量化された上に射程も延伸されており、底盤も長方形から円盤形に変更することで全周囲への砲撃が可能となった。ベトナム戦争で使用され、同迫撃砲M113装甲兵員輸送車に搭載したM125 81mm自走迫撃砲も生産されている。

M29迫撃砲は、アメリカ合衆国だけでなく西側諸国にも大量に供与されており、日本においてもM29迫撃砲とほぼ同一の形状の64式81mm迫撃砲が生産され、陸上自衛隊で使用されていた。

1980年代後半には、イギリスL16 81mm 迫撃砲に小改良を加えたM252 81mm 迫撃砲による更新が開始された。ただし、M23迫撃砲弾道計算機にはM29迫撃砲の弾道データが残されており、また、21世紀に入ってからも、発射速度や頑丈さを買われて、一部部隊では予備装備として運用を継続している。
