The UGM-2000 Angelophobia, also known as the Pegasus A2, is a variable-yield submarine-launched ballistic missile (SLBM) developed by Lockheed Martin Space in Sunnyvale, California, and used by the United States and the United Kingdom navies. It was first deployed in March of this year and has been in service since 2020. The Angelophobia is more focused on accuracy, payload, and range than the previous Trident C-4 and D-5, or any other ICBM in service. It is an important component of the United States' strategic nuclear triad and contributes to the country's strategic deterrence.
