CH-46"海骑士"运输直升机(Sea Knight)首飞于1958年,正式服役于美国海军则在1960年.担任运输物资人员等任务.虽然并非是特种作战飞机却经常执行一些特种行动.

CH-46直升机是美国海军陆战队最主要的战斗攻击直升机之一,这种直升机外形有点像公共汽车,双螺旋桨,海军陆战队主要用它把部队从舰上运到岸上,或把部队从营地运到作战前沿位置。而美国海军则用这种直升机把装备运到舰上或执行搜索与救援任务。

CH-46直升机由美国“波音公司”制造,1964年服役,使得它比现在驾驶它的大部分飞行员年龄都要大。但在整个服役期内,CH-46直升机问题多多,命运时起时落。由于时间太长,老是出现一些故障。由于故事频繁,加上又不能弃之不用,所以美军只得经常进行检查,而且海军陆战队下令每架CH-46每次只能载12人而不是原来规定的25人,所以现在每小时飞行的代价比以前上升了75%。

在越南战争期间,这种直升机发挥了极大的作用。CH-46初次服役是在越南战争时期,一开始用于从海军舰只上向陆上运送部队和货物,或者从陆上送到舰上,另外还执行了成千上万次救护受伤陆战队员的任务。自从越战以来,CH-46几乎参加了所有美军大型的军事行动,包括2001年的阿富汗战争,以及正在进行的对伊战争。

Mission: The mission of the CH-46E Sea Knight helicopter in a Marine Medium Helicopter (HMM) squadron is to provide all-weather, day/night, night vision goggle (NVG) assault transport of combat troops, supplies, and equipment during amphibious and subsequent operations ashore. Troop assault is the primary function and the movement of supplies and equipment is secondary. Additional tasks are: combat and assault support for evacuation operations and other maritime special operations; over-water search and rescue augmentation; support for mobile forward refueling and rearming points; aeromedical evacuation of casualties from the field to suitable medical facilities.

Background: The CH-46 Sea Knight was first procured in 1964 to meet the medium-lift requirements of the Marine Corps in Viet Nam with a program buy of 600 aircraft. The aircraft has served the Marine Corps in all combat and peacetime environments. However, normal airframe operational and attrition rates have taken the assets to the point where a medium lift replacement is required. The safety and capability upgrades are interim measures to allow continued safe and effective operation of the Sea Knight fleet until a suitable replacement is fielded.
