ISA Cruisers are the most advanced ships in the ISA Navy and are manufactured by the ISA Vekta Shipbuilding Division.


Measuring 550 meters in height[1] and propelled by nuclear-powered beam thrusters that double as weapons, Cruisers provide the ISA with the persuasive force it requires to keep rebelling planets in line. Each ISA Cruiser holds a complement of 7,600[1], including 5,000 Marines[1], 600 pilots[1], 1,800 support crew[1], and 200 officers[1]. In addition, it can store up to 160 Intruder-type landing craft[1] and 30,000 metric tons of ammunition[1] for the ship's main defense cannons. Cruisers also have 'dispersive armor'[2] which can handle repeated hits from enemy ships, and even provide some defense against the heavy main cannon of the Helghast MAWLR.

Designing and constructing the Cruiser was a massive undertaking for the ISA engineers. These ships differ greatly from their UCA counterparts, as they can change their positioning in-flight from combat operations in space to acting as on-station support in atmospheric conditions. An automated deployment system allows the Cruisers to rapidly send Intruder troop transports to a planet's surface, ensuring total planetary containment.


These towering hulks carry enough firepower to level a city several times over. Weapons onboard include:

  • 'Snow Missiles' [3], long-range missiles capable of disintegrating entire enemy vessels in a few shots.
  • M10 Quad Cannons[4], anti-aircraft cannons with four automatic 35x228mm guns, and includes an additional guided missile launcher.
  • Bombardment Laser[5], which is prow-mounted for pinpoint orbital to ground strikes.

In ship-to-ship combat, the ISA Cruiser completely outmatches Helghast Cruisers, a single cruiser is capable of destroying an entire Helghast battle-group with a single missile barrage. Generally, the only effective means the Helghast have of engaging ISA Cruisers are boarding parties, ground-based orbital defense weapons, or just having a larger number of Cruisers in order to overwhelm them.

  • The ISA Cruiser are designed to resemble a hanging sword. Their presence in Killzone 2 echoes to the Sword of Damocles story, as the cruisers ominously hung over the Helghast capital of Pyrrhus and their leader Scolar Visari.[1]
  • Miguel Martinez designed the ISA Cruiser to have a realistic, functional look based on real-life naval cruisers, aircraft carriers, space shuttles, and rockets.[1]
