Lindas fotos! Pero no se ven las Goalkeepers. Falta que corra agua bajo el río, pero en fin, si no llegan, a falta de pan buenas son las tortas y tenemos/tendremos fácil acceso a Phallanx.
Veamos que dice el oráculo San Wikipedia sobre el Goalkeeper y Phallanx:

From Wikipedia, the free encyclopedia.
Goalkeeper CIWS
Goalkeeper is a Dutch close-in weapon system, the purpose of which is to defend a ship against incoming missiles and ballistic shells. The system consists of a 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 position. The system is made by Thales Navy Netherlands, and over 50 have been produced. The system can also be deployed to protect airfields.
Development
Development of the system began in 1975 with Hollandse Signaalapparaten working with General Electric, who supplied the GAU-8 gun. A prototype, the EX-83 was first demonstrated to the Dutch Navy in 1979. The system entered service with the Royal Navy in 1980.
Description
The system first acquires a target using the 2D X-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 X-Band and Ka-Band, this enables the engagement radar to use the search radars signal to find the target quickly without additional searching, also data from the X-Band and Ku-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 GAU-8/A Avenger 30 mm gun, as used 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.
The systems reaction time to a Mach 2 sea-skimming missile from automatic detection to kill is reported to be 5.5 seconds with the engagement starting at a range of 1500 m and ending with a kill at 300 m.
The Chinese appear to have developed a very similar weapon, possibly a copy, called the Type 730.

Comparison to Phalanx
The Phalanx CIWS system is another system that is widely used in the same role, there are several key differences between the two systems:
Goalkeepers 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 can only track and engage one target at a time, while Goalkeeper can track 18 targets and switch to engage the greatest threat.
Both weapons have similar maximum ranges, however Goalkeepers kill distance is reportedly a slightly further (500 to 350 meters compared to 300 meters for the Phalanx).
Phalanx ammo drum is mounted directly on the gun, the Goalkeeper is reloaded from below deck.

Phalanx CIWS
The Phalanx CIWS (Close-in weapon system, pronounced see-whizz) is an anti-missile system designed and manufactured by Raytheon Company. It is used by the United States Navy on every class of surface combat ship in its fleet and is used by navies of over twenty allied nations.
It was developed as the final line of defense (terminal defense) against anti-ship missiles (AShMs), including high-G, maneuvering sea-skimmers. The first system was offered to the US Navy for evaluation on the USS Bigelow in 1977. It was accepted and production started in 1978, the first ship fully fitted out was the Coral Sea in 1980.
The basis of the system is a 20mm M61 Vulcan gatling gun linked to a radar system for acquiring and tracking targets. The gun fires at a variable 3,000/4,500 shots per minute (early models only fired 3,000 rounds per minute): it is mounted in a self-contained turret along with an automated fire control system. The system automatically searches, detects, tracks, engages and confirms kills using its computer-controlled radar system. The entire unit weighs 5625 kg or 6120 kg.
Phalanx CIWS firing
Phalanx has been developed through a number of different configurations. The basic style is the Block 0. The Block 1 (1988) offers various improvements in radar, ammunition, rate of fire and computing. Block 1A introduced a new computer system. The Block 1B PSuM (Phalanx Surface Mode, 1999) adds a forward looking infrared (FLIR) sensor to allow the weapon to be used against surface targets. This addition was developed to provide ship defense against small vessel threats and other "floaters" in littoral waters and to improve the weapon's performance against slower low-flying aircraft. The Block 1B also allows for human intervention to identify and target threats.
The US Navy uses armor-piercing penetrator rounds, originally depleted uranium but now tungsten. All Phalanx systems hold 1500 rounds in their magazines.
The US and Canada are in the process of upgrading all their Phalanx systems to the Block 1B configuration. The Block 1B is also used by other navies such as Japan, Egypt and Bahrain.
Many sailors familiar with the system refer to it as R2-D2.
Phalanx in combat (at sea)
The Phalanx system has not been credited with shooting down any enemy missiles or aircraft.
In February 1991, during the first Gulf War, the USS Missouri and the Phalanx-equipped USS Jarrett were in the vicinity of an Iraqi Silkworm missile that had been fired, either at Missouri or at the nearby HMS Gloucester. After Missouri fired a bundle of chaff, the Phalanx system on Jarrett, operating in the automatic target-acquisition mode, fixed upon the chaff and fired a burst of rounds. Four rounds hit Missouri, which was two to three miles from Jarrett at the time. There were no injuries.[1]
Phalanx in combat (ashore)
Land-Based Phalanx Weapon System
The U.S. Army's version of the Navy's CIWS Phalanx anti-missile system is called the "Land-Based Phalanx Weapon System" (LPWS). It is a type of "C-RAM" (counter-rockets, artillery and mortars).
The naval Phalanx systems fire depleted uranium or (more recently) tungsten armor-piercing rounds. On the high seas, all these heavy rounds falling to the surface aren't much of a problem. But in crowded urban environments this would present a very serious danger to friendly forces and civilians. So instead of using the AP ammunition, the C-RAM uses the HEIT-SD (High-Explosive Incendiary Tracer, Self-Destruct) ammunition originally developed for the M163 Vulcan air-defense system. These rounds explode in mid-air, raining shrapnel at the incoming rounds in order to destroy or deflect them. (From
