It stars Steven Seagal (who also produced the film), Tommy Lee Jones, Gary Busey, and Erika Eleniak.

The battleship USS Missouri (BB-63) arrives at Pearl Harbor, where then-President George H. W. Bush announces that the ship will be decommissioned in California.

Unable to imprison Ryback in the brig without the captain's approval, Krill detains him in the walk-in fridge, placing Marine Private Nash on guard.

The band and caterers are mercenaries led by disillusioned former CIA operative William Strannix, who, aided by Krill, takes over the ship.

Strannix's mission is to steal the ship's Tomahawks and load them onto a hijacked North Korean submarine as revenge for the CIA attempting to assassinate him.

Krill activates the fire suppression system to flood the forecastle and force Ryback to rescue his mates while setting an ambush.

Ryback shuts down Missouri's weapon systems to allow incoming Navy SEALs to land, but the submarine crew shoots down the helicopter carrying the team.

Aided by a gunner's mate, Ryback attacks the submarine using the battleship's 16-inch guns, killing Krill and everyone on board.

Ryback kills Strannix in a knife fight and then uses the launch code disk to destroy the Tomahawk missiles.

[10] Gary Busey claimed in later interviews that Seagal sexually harassed Erika Eleniak, who co-starred with Anderson on Baywatch, on set.

The site's consensus states: "A well-directed action thriller that makes the most of its confined setting, Under Siege marks a high point for early '90s action—and its star's spotty filmography.

[28] A sequel, Under Siege 2: Dark Territory, was released on July 14, 1995, with Seagal, Romano, Mancuso and Dye reprising their roles.

In November 2021, a reboot of the original was in development for HBO Max, with Timo Tjahjanto and Umair Aleem attached to direct and write the film.
