The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance.

Mk46-5鱼雷是20世纪70年代末按全新设计方案研制的，是Mk46重的最新型号，其自导系统的改进提高了检测灵敏度和鱼雷再搜索能力，并可识别诱饵假目标。 良好的推进系统不仅增大了航程，还降低了自噪声。 该鱼雷不仅可以进行深水反潜，浅水作战也不错。 [1] 由美国霍尼韦尔公司在20世纪50年代末60年代初研发的一种主要用于攻击高性能潜艇的轻型鱼雷。 该鱼雷速度高、攻击深度大，具备主动及被动声音导向功能。

Mk 46型魚雷於1960年代開發，取代Mk 44型魚雷任務的反潛艦用輕型魚雷；是美國海軍輕型反潛作戰魚雷庫存的骨幹，也是北約的標準。 這些 航空魚雷 旨在攻擊高性能 潛艇 。

The Mk 46 is a gas-operated, air-cooled, belt-fed lightweight machine gun (LWMG) in use with United States special operations forces (SOF) since 2003. It is a variant of the M249 SAW light machine gun that has been designed by Fabrique Nationale (FN) to be as light and compact as possible and was tailored specifically for use by SOF.

The 5.56x45mm FN® MK 46 MOD 1 is the lightweight U.S. special operators’ variant of the FN® M249 Squad Automatic Weapon (SAW). The MK 46 MOD 1 incorporates improved receiver pins, a feed tray with retention pawls and a vented hand guard with improved heat shield and three MIL-STD-1913 rails.

MK46是最早采用数字计算机的自导鱼雷，也就是说它可以按照预定的程序搜索目标，发射后，MK46先是以45°角下潜接敌，到达预定深度时，按蛇形（主动自导）或环形（被动自导）方式搜索，捕获目标后，用主动自导方式转入追击，如目标丢失则重新进入蛇形或者环形搜索状态，直至重新发现目标或燃料耗尽为止，这种主被动联合声导模式非常先进。 反观我国，当时即使是在研的鱼3用的也只是单一的被动声自导手段，对目标辐射的噪声有很强的依赖性，很容易脱靶。 …
