QF 17 pdr Mk I-II의 사진 갤러리, 병기 퀵 파이어 17 주 (또는 단지 17-pdr) 차 세계 대전 동안 영국에 의해 개발 된 76.2 mm (3 인치) 총이었다. 그것은 자신의 마차에 대전차 총으로 사용되었다, 뿐만 아니라 영국 탱크의 숫자를 장착. 그것은 전쟁의 가장 효과적인 연합군 대전차 총이었다. APDS 샷에 사용되어 독일 전차에서 가장 두꺼운 갑옷을 제외한 모든 장갑을 물리칠 수 있었습니다. 특히 미국 M4 셔먼 전차의 셔먼 반딧불이 변종을 생산하는 데 사용되어 영국 전차 부대가 독일 전차에 대항하여 자신들을 보유할 수 있는 능력을 제공했다. 대전차 역할에서 전쟁 후 120mm BAT 반동없는 소총으로 대체되었다. 탱크 건으로 84 mm 20 pounder에 의해 계승 되었다.

The Most Formidable Anti-Tank Gun of the West
Tthe Ordnance QF 17-pounder was arguably the finest Allied anti-tank gun of World War II. Developed in 1941 to counter the increasing thickness of German armor, it surpassed the earlier 2-pdr and 6-pdr guns in every metric. While the 맥 I was the standard towed version on a split-trail carriage, the 엠케이 II (and subsequent Marks) were optimized for use in tanks and tank destroyers. It was the only Allied gun capable of consistently knocking out a Tiger or Panther at combat ranges, making it the most feared weapon in the British arsenal.

Design Engineering: High Velocity and Sub-Caliber Power
- The Muzzle Brake: Due to the massive propellant charge required to fire such a heavy shell at high speeds, the 17-pdr produced a violent recoil. A large, double-baffle muzzle brake was essential to dissipate the gases and prevent the gun from leaping off the ground.
- APDS (Sabot) Technology: The 17-pdr pioneered the use of Armor-Piercing Discarding Sabot (APDS) ammunition. By firing a smaller tungsten core inside a lightweight sleeve that fell away after leaving the barrel, the projectile achieved incredible velocities (over 1,200 m/s), allowing it to punch through the front of a Tiger II.
- The “Pheasant” Expedient: When the 17-pdr barrels were ready before their proper carriages were, the British mounted them on 25-pounder howitzer carriages. These hybrid guns, known as “Pheasants,” were rushed to North Africa just in time to surprise German Tiger tanks at Medenine.
- Mk II Integration: To fit this massive gun into a tank turret (like the Sherman Firefly), the recoil system had to be completely redesigned. The Mk II variant featured a shorter recoil stroke and turned the gun 90 degrees on its side to allow the loader to access the breech more easily in cramped conditions.
Operational History: Breaking the Panzers
- The Firefly Legend: Perhaps the most famous use of the 17-pdr was in the 셔먼 반딧불이. This gave British and Commonwealth armored units a tank that could finally kill German heavies from the front, forcing German tank commanders to target the “long-barreled Shermans” first.
- Northwest Europe: From D-Day to V-E Day, the 17-pdr was the primary “door kicker.” Whether towed by a Crusader tractor or mounted on the 아킬레스건 그리고 아처 tank destroyers, it provided the lethal reach needed to halt German counter-attacks.
- Massive Signature: The downside of its power was the muzzle blast. Firing the 17-pdr kicked up so much dust and debris that it instantly gave away the gun’s position and often blinded the crew for several seconds after the shot.
- Post-War Service: The 17-pdr was so effective it remained in service long after the war, seeing action in the Korean War and serving as the primary armament for the early Israeli tank corps.
