Goalkeeper is a Dutch close-in weapon system, which defends ships against incoming missiles and ballistic shells. The system consists of an autocannon and an advanced radar which tracks incoming fire, determines its trajectory, then aims the gun and fires in a matter of seconds. The system is fully automatic, needing no human input once activated. The name comes from the soccer/football position. The system is made by Thales Navy Netherlands, and over 50 have been produced. The system can also be deployed to protect airfields. Goalkeeper CIWS File history Legend: (cur) = this is the current file, (del) = delete this old version, (rev) = revert to this old version. ...

Development Development of the system began in 1975 with Signaal (now Thales Nederland) working with General Electric, who supplied the GAU-8 gun. A prototype, the EX-83 was first demonstrated to the Royal Netherlands Navy in 1979. Thales Nederland B.V.

Description The system first acquires a target using the 2D I band search radar, which can track up to 18 targets at once. The engagement radar is then slewed to the heading indicated by the search radar. The engagement radar operates in both I band and K band, this enables the engagement radar to use the search radars signal to find the target quickly without additional searching, also data from the I band and K band return signals can be compared to increase resistance to ECM and clutter. The engagement radar is also backed up by an optical system. The I band is the range of radio frequencies from 8 GHz to 10 GHz in the electromagnetic spectrum. ...

The GAU-8/A Avenger 30 mm gun, as used by the A-10 Thunderbolt II was selected for the system, primarily because, although the muzzle velocity and range are similar to the M61 Vulcan, the projectiles are much heavier (430 grams compared to 100 grams). This is critical because supersonic missiles that are damaged may still have enough momentum to hit the ship—the only way to ensure the protection of the ship is either detonate the warhead of the missile or obliterate the missile.

Comparison to Phalanx The Phalanx CIWS is another system that is widely used in the same role, there are several key differences between the two systems: Block 1 CIWS The Phalanx CIWS (Close-in weapon system, pronounced see-wiz) is an anti-missile system that was designed and manufactured by the General Dynamics Corporation, Pomona Division. ...
- Goalkeeper's projectiles are much larger (30 mm versus 20 mm) and have greater kinetic energy.
- Goalkeeper is twice as expensive as the Phalanx.
- Phalanx can be welded to any section of deck and plugged in, while Goalkeeper requires significant 'deck penetration' and integration.
- Phalanx ammo drum is mounted directly on the gun, the Goalkeeper is reloaded from below deck.
- Phalanx can only track and engage one target at a time, while Goalkeeper can track 18 targets and switch to engage the greatest threat.[citation needed]
- Both weapons have similar maximum ranges, however Goalkeepers kill distance is reportedly slightly further (350 to 500 meters compared to 300 meters for the Phalanx).
Kinetic energy is the energy by virtue of the motion of an object. ...
