TERCOM

However, with the advancement of technology, the possibility of a new cruise missile arose in the mid-1970s. The emergence of small, lightweight turbofan engines as propulsion engines enabled small, lightweight, long-range cruise missiles because they consumed less fuel even when flying at low altitudes and low speeds. By connecting the radio altimeter and the control unit via a computer, it became possible to fly at extremely low altitudes, making it harder for the enemy to detect them. Errors that occur in the inertial guidance system during long flights can be corrected by adopting guidance technologies such as terrain contour matching (abbreviated TERCOM), which will be described later, and this has dramatically improved the accuracy of the missile's impact. In the United States, B52 strategic bombers equipped with air-launched cruise missiles using these technologies were deployed in combat from the end of 1982, and at the end of 1983, the deployment of Tomahawk cruise missiles for attacking ground targets launched from the ground began, followed by the deployment of Tomahawks for surface ships and submarines.

…しかし,その後技術の進歩に伴い70年代中ごろから新しい巡航ミサイルの可能性が生じた。すなわち,推進用エンジンとして小型・軽量のターボファンエンジンが出現し,低空を低速で飛行しても燃料消費が少ないため,小型・軽量で長射程の巡航ミサイルが可能になったこと,電波高度計と操縦装置をコンピューターを介して連結することにより,超低空を飛行できるようになり,相手に発見されにくくなったこと,長時間飛行中に慣性誘導装置に生ずる誤差を,後述する地形等高線照合技術terrain contour matching(略号TERCOM(ターカム))等の誘導技術の採用により補正し,弾着精度を画期的に向上できるようになったこと,などによる。アメリカではこれらの技術を用いた空中発射巡航ミサイルを搭載したB52戦略爆撃機を82年末から実戦配備し,83年末には地上から発射する地上目標攻撃用〈トマホーク〉巡航ミサイルの配備を開始し,引き続き水上艦,潜水艦搭載用〈トマホーク〉の配備を進めた。…
