Trident I C-4 FBM / SLBM 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.

The Trident was built in two variants: the I (C4) UGM-96A and II (D5) UGM-133A; however, these two missiles have little in common. While the C4, formerly known as EXPO (Extended Range Poseidon), is just an improved version of the Poseidon C-3 missile, the Trident II D-5 has a completely new design (although with some technologies adopted from ...

2024年8月11日 · The UGM-93A Trident I (C-4) was a three-stage U.S. submarine-launched ballistic missile with a range of about 4,000 nautical miles, double that previous generation Poseidon C-3. This allowed the C-4 to be the first missile that could reach Soviet targets from ports in the United States.

2024年3月9日 · 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.

1996年3月31日 · 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.

三叉戟I C4导弹 是美国海军部署的持续时间最长的舰队弹道导弹。Trident I C4导弹采用先进的推进剂，微电子和新型减重材料技术，结合了其前身Poseidon的多种独立目标处理能力，并提供了超过4,000海里的完整有效载荷。

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.
