The M1901 Zinko Nuclear Missile, or more simply known as just the Zinko Nuclear Missile after its designer Robert Zinko, was developed in 2552 as a ship-to-ship munitions intended to replace the aging SHIVA class missile. The Zinko has a variable blast yield which can range from 10 to 30 megatons and features a lithium triteride casing. They were found on many ships in the UNSC, such as the UNSC Las Vegas. Later in the design phase, a variant of the original Zinko was developed to serve as a ICBM.
