The TRIDENT I (C-4) is a submarine-launched ballistic missile (SLBM) developed to replace the Poseidon missile in existing strategic missile submarines and to arm the OHIO class SSBNs. It...

Mar 9, 2024 · The Trident I C-4 Submarine-Launched Ballistic Missile (SLBM) initially referred to as EXPO (extended range POSEIDON) was designed to supplant the Poseidon/Polaris missiles. Development began in 1971, culminating in a missile that offered increased range capability over its predecessor, the Poseidon C3, with approximately the same physical size.

The UGM-96 Trident I, or Trident C4, was an American submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space Systems in Sunnyvale, California. First deployed in 1979, the Trident I replaced the Poseidon missile.

三叉戟飛彈 （Trident missile）是 美國 洛克希德·马丁 製造的 潛射彈道飛彈 （SLBM），於1980年代和90年代分別替代 海神飛彈 和 北極星飛彈。 主要型号包括三叉戟I型（UGM-96 Trident I）和II型（UGM-133 Trident II）。 三叉戟飛彈部署在 美國海軍 14艘 俄亥俄級核潛艇 上，每艘可攜帶24枚。 根據 美英共同防禦協定，三叉戟飛彈也出售給英國，部署在 英國皇家海軍 4艘 前卫级核潜艇，每艘可攜帶16枚。 不過，英軍的三叉戟飛彈會採用英國核彈頭。 兩國的新一代潜艇 哥倫 …

The Trident I (C4) was deployed in 1979 and was phased out in the early 2000s. Trident II (D5) has been deployed since 1990 and has been designed for an ~30-year life, or until 2027. The following section describes APL’s efforts to develop and continually improve a testing and evalu-ation program that is useful to and concurrent with

Mar 31, 1996 · The current Fleet Ballistic Missile (FBM) C4 and D5 systems, shown in Figure 1, were developed with engineering software tools and methodologies over a 40 year period. These tools and methods were often specifically tuned (tailored) to a specific missile configuration and to the available ground and flight test data.

To achieve a 4000 nm range [ versus the 2500 nm range of the POSEIDON C3] the Trident I (C4) is a three-stage solid-propellant missile with basically the same envelope dimension as a C3 (e.g.,...

SSBN-640 Benjamin Franklin-Class FBM Submarines. Generally similar to the SSBN-616 Lafayette-class, the twelve Benjamin Franklin (SSBN-640)-class submarines had a quieter machinery design, and were thus considered a separate class. Lockheed commenced the TRIDENT I (C4) program in November of 1973 with the missile's IOC date established as 1979.
