TUCSON, Ariz., Oct. 23, 2015 /PRNewswire

 

The U.S. Navy awarded Raytheon Company (NYSE: RTN) a $159.9 million contract to manufacture, inspect and test Phalanx Close-in Weapon Systems (CIWS).

 

Phalanx 1B encompasses the range of actions required to assure success and shape the battlespace for naval, joint, and combined forces. The contract, which provides for a $10 million option in FY15 and another valued at $291 million in FY16, includes support equipment for the Phalanx and SeaRAM Weapon Systems, Block 1B radar upgrades and kits for reliability, maintainability, and availability. The contract also covers overhaul of four Land-based Phalanx Weapon Systems. "Phalanx provides the U.S. Navy's ships with a 'last-chance' defense against anti-ship missiles and littoral warfare threats while SeaRAM extends that inner-layer battlespace," said Rick Nelson, vice president of Raytheon's Naval and Area Mission Defense product line. "Close-in systems give warfighters the ability to automatically carry out functions usually performed by separate systems on other ships." Work under the contract, which was signed in the third quarter of 2015, is expected to be completed by August 2018 in Louisville, Kentucky. This contract was announced by the Department of Defense on September, 30, 2015.

 

Close-in Defense Solutions

Phalanx is a rapid-fire, computer-controlled radar and 20 mm gun system that automatically acquires, tracks and destroys enemy threats that have penetrated all other ship defense systems. More than 890 systems have been built and deployed in navies around the world.

Intended to enlarge Phalanx's keep-out range against evolving anti-ship missiles, rotary- and fixed-wing aircraft and other threats, SeaRAM Anti-ship Missile Defense Systems use advanced Phalanx Block 1B sensors and replaces the gun with an 11-round Rolling Airframe Missile guide. SeaRAM is aboard the Independence-class of the U.S. Navy's Littoral Combat Ships.

Surface Forces: China Perfects A New 30mm Anti-Missile Defense

 

January 13, 2015: Strategy Page

 

The Chinese Type 1130 multibarrel autocannon has been confirmed as the final production version of what was previously called the Type 1030. The 1130 has 11 barrels (one more than the 1030) and two magazines carrying over 1280 rounds of ammo. That is enough to engage over 40 targets before needing a reload. Top rate of fire is 10,000 rounds a minute (166 per second). This robotic weapon is radar controlled and, when turned on, automatically fires at incoming targets while under software control. It is similar in function to the U.S. Phalanx. The 1130 has five times more ammo ready-to-fire than the 1030 along with many refinements added during years of development. Because of its size, weight and large power requirements the Type 1130 is only installed on carriers and large destroyers.

 

This new weapon was first spotted in 2011 when the new Chinese aircraft carrier, the Liaoning (formerly Varyag) was seen with at least two of the then-new “Type 1030” automatic cannon systems. The Type 1030 appeared to be an upgraded (to ten barrels) model of the older Type 730 (seven barrel) and Type 630 (six barrel), close-in anti-missile automatic cannon. All fire 30mm shells at incoming anti-ship missiles, aircraft or anything else deemed a danger to the ship. The 1030 turned out to be still in development and the final version was the 1130.

 

Also seen on the Liaoning in 2011 were four 18 cell launcher for FL-3000N anti-missile missiles. The FL-3000N is similar to the American RAM anti-missile missile system, except that they come in 24 missile and 18 missile launchers and are less accurate. FL-3000N was only introduced in 2008, and uses smaller missiles than RAM. The FL-3000N missiles have a max range of nine kilometers (about half that for very fast incoming missiles). The 120mm, two meter long missiles use a similar guidance system to RAM, but are not as agile in flight.

 

Missiles are increasingly preferred over cannon for short range anti-missile defense. Thus over the last decade, the U.S. Navy Phalanx 20mm autocannon anti-missile system has been more frequently replaced by SeaRAM. What's interesting about this is that SeaRAM is basically the Phalanx system, with the 20mm gun replaced with a box of eleven RAM (RIM-116 "Rolling Air Frame") missiles. The Phalanx was developed in the 1970s, and entered service in 1977 (about the same time as the original Russian Type 630).

 

RAM was developed in the 1980s, and didn't enter service until 1993. RAM has a longer range (7.5 kilometers) than the Phalanx (2-3 kilometers, or 3.5 kilometers for the 30mm weapons) and was originally designed to be aimed using the ship's fire control systems. Phalanx, on the other hand, has its own radar and fire control system and, once turned on, will automatically fire at any incoming missiles. The latest Type 630/730/1130 operate the same way. This is necessary, as some anti-ship missiles travel at over a 500 meters a second. With SeaRAM, you've got a little more time, and can knock down the incoming missile farther from the ship. This is important, because it was feared that a large, very fast anti-ship missile (which the Russians prefer, and sell to foreigners), even when shot up by Phalanx, might still end up having parts of it slam into the target ship. Since SeaRAM has eleven missiles ready to fire, it can also engage several targets at once, something the Phalanx could not do.

 

The RAM missiles are 127mm in diameter, three meters (9.3 feet) long and weigh 73.6 kg (162 pounds) each. The terminal guidance system is heat seeking. Basically, it uses the rocket motor and warhead from the Sidewinder air-to-air missile, and the guidance system from the Stinger shoulder fired anti-aircraft missile. SeaRAM missiles cost about $450,000 each, which is probably at least 50 percent more than the FL-3000N missiles. SeaRAM is meant to provide protection for combat support ships that normally have no defenses, or at least no combat radars and fire control system. The new LCS will use the SeaRAM as well.

 

Like most modern carriers, the only weapons carried are anti-missile systems like Type 1130 and FL-3000N, plus some heavy machine-guns (which are often kept inside the ship, and mounted outside only when needed.) However, Russian practice was been to sometimes install long range anti-ship missiles as well. China may also do this with Shi Lang.

Babcock converting Phalanx for use of British carrier

 

LONDON, Dec. 17 (UPI)

 

Phalanx Close-In Weapon Systems are being converted back to their maritime configuration and upgraded for use on the Royal Navy's new Queen Elizabeth aircraft carrier

 

Phalanx Close-In Weapon Systems are being converted back to their maritime configuration and upgraded for use on the Royal Navy's new Queen Elizabeth aircraft carrier

Britain's new aircraft carrier, the Queen Elizabeth, is to be fitted with Raytheon's Phalanx weapon systems for close-in defense.

The three systems for the carrier will be provided by British engineering firm Babcock International, in association with Raytheon, which will deliver and install Phalanx 1B kits to convert the systems to their original configuration for maritime use. The kit also upgrades the system.

Babcock said a kit for a fourth Phalanx system will be delivered under the Ministry of Defense contract.

Babcock is the in-service support provider to the Ministry of Defense for Phalanx systems, managing and performing all support activities and providing logistics support for spares and repairable units. It said it will procure the Phalanx 1B systems in partnership with Raytheon, and will also undertake the land-based Phalanx weapon system conversions using Babcock weapons support engineers.

The systems are to be delivered by March of next year.

"Following the successful on-schedule delivery of a similar contract last year, we are delighted to have this further opportunity to apply our expertise and work with Raytheon to help the MOD and Royal Navy build the Phalanx CIWS capability it needs."

Phalanx CIWS is a rapid-fire, computer-controlled radar and 20mm Gatling gun system. The Phalanx 1B upgrade incorporates a side-mounted Forward Looking Infra-Red Camera that enables the system against surface targets and slow air targets in addition to anti-ship missiles.

Navy taps Raytheon for work on Phalanx



TUCSON, June 12 - By Richard Tomkins (UPI)

 

The U.S. Navy has contracted Raytheon to remanufacture and upgrade its Phalanx Close-in Weapon System for use on Independence-class Littoral Combat Ships.

 

Raytheon reports it has received a U.S. Navy contract to remanufacture, overhaul and provide upgrades to Phalanx Close-in Weapon Systems.

The contract is worth $115.5 million, the company said. Work on the 20mm system is expected to be completed in late 2017.

Phalanx, with a computer-controlled radar, is a Gatling gun system that automatically acquires, tracks and destroys enemy threats that have penetrated all other ship defense systems. It has an effective range of 2.2 miles and a firing rate of 4,500 rounds a minute.

UK MoD receives additional Babcock Phalanx systems

 

8 May 2014 naval-technology.com

 

The UK Ministry of Defence (MoD) has taken delivery of four additional Babcock Phalanx 1B kit modifications and two conversions of the land-based Phalanx weapon system, in the upgraded marinised configuration.

 

These systems form part of a contract awarded in 2006 to manage and execute all maintenance support activities, such as a 24/7 helpdesk for the Royal Navy, as well as logistics support for spares and repairable units.

 

Babcock has worked with Phalanx 1B systems' original equipment manufacturer Raytheon to convert the two land-based systems using their own support engineers.

 

Babcock weapons business development manager Martin Laity said: "We are pleased to have been able to deliver this further Phalanx capability upgrade successfully and on time, in partnership with Raytheon and the MoD, to enable the MoD and Royal Navy [to] build up the Phalanx close-in weapon systems (CIWS) capability it needs."

 

As part of an on-going programme in collaboration with Raytheon and the International Guns Missiles and Rockets Project Team, Babcock is also under contract to modernise 16 Phalanx systems to the 1B configuration.

 

Acting as the UK's primary defence for ships against the threat of anti-ship missiles, Phalanx CIWS is a rapid-fire, computer-controlled radar and 20mm Gatling gun system.

 

Incorporating a side-mounted forward looking infra-red camera (FLIR), the upgraded Phalanx 1B weapon system enables the CIWS to guard the ship against surface targets, while slowing air targets and anti-ship missiles.

 

Furthermore, the 1B configuration also plays a vital role in terms of countering the threat from small surface craft in littoral waters.
