Raytheon livre le 1er système d'armes RAM Block 2 (Rolling Airframe Missile) à l'US Navy

Raytheon livre le 1er système d'armes RAM Block 2 (Rolling Airframe Missile) à l'US Navy | Newsletter navale | Scoop.it

TUCSON, Ariz., Aug. 27, 2014 Raytheon Company (NYSE: RTN) delivered the first Block 2 variant of its Rolling Airframe Missile system to the U.S. Navy as part of the company's 2012 Low Rate Initial Production contract.  RAM Block 2 is a significant performance upgrade featuring enhanced kinematics, an evolved radio frequency receiver, and an improved control system.

"As today's threats continue to evolve, RAM Block 2's enhanced features give an unfair advantage to naval warfighters across the globe," said Rick Nelson, vice president of Raytheon Missile System's Naval and Area Mission Defense product line.  "Along with demonstrating a long-standing international partnership, the RAM program has a record of 91 consecutive months of contractual on-time deliveries, and continues its remarkable success rate of over 90 percent during flight tests."

RAM is a cooperative program between the U.S. and German governments with industry support from Raytheon and RAMSYS of Germany. The RAM Cooperative program has been in place for over 30 years and has enjoyed excellent integration and technology sharing between both countries.

The initial Block 2 delivery milestone was marked by a ceremony at Raytheon Missile Systems that was attended by U.S. and German naval dignitaries, and Raytheon leaders and RAM program and team members.

About RAM

RAM is a supersonic, quick reaction, fire-and-forget missile providing defense against anti-ship cruise missiles, helicopter and airborne threats, and hostile surface craft. The missile's autonomous dual-mode, passive radio frequency and infrared guidance design provide a high-firepower capability for engaging multiple threats simultaneously. RAM is installed, or planned for installation, aboard more than 165 ships as an integral self-defense weapon for the navies of Egypt, Germany, Greece, Japan, the Republic of Korea, Turkey, the United Arab Emirates and the United States.

L'US Navy accepte le nouveau Rolling Airframe Missile RAM Block 2 qui entre en production de pré-série

L'US Navy accepte le nouveau Rolling Airframe Missile RAM Block 2 qui entre en production de pré-série | Newsletter navale | Scoop.it

The Navy is getting ready to accept its first Block 2 Rolling Airframe Missiles (RAM) for ship defense — a new variant of the self-guided missiles now protecting a wide range of Navy ships including amphibious assault ships and the Littoral Combat Ship, service officials said.

“RAM provides the self-defense against cruise missiles, aircraft and small surface threats. It has a dual mode RF and IR guidance system that will guide it right to an inbound target,” said Jeffrey Meyer, business development manager, Raytheon.

The Block 2 RAM, now in low-rate-initial production, will be delivered to the Navy toward the end of the summer, Raytheon officials said.  Overall, the Navy plans to acquire at least 502 RAMs between 2015 and 2019, said Lt. Robert Myers, a Navy spokesman.

The new Block 2 variant includes a new RF receiver, new navigation system and increased diameter to 6-inches, Raytheon officials said. The new missile variant also includes enhanced guidance algorithms and a more powerful dual-thrust rocket motor enabling the missile to reach longer ranges, Raytheon officials said.

The Block 2 missile is 9.45 feet long, weighs 194-pounds, and is able to reach supersonic speeds, according to Raytheon and Navy information.

The missile is able to intercept threats that are close to the surface by sea-skimming or diving in onto a target from a higher altitude, Meyer explained. The so-called kinematic or guidance improvements of the Block 2 missile give it an improved ability to counter maneuvering threats, Navy and Raytheon officials explained.

The RAM missile, designed to destroy incoming threats from within the horizon but not in the immediate vicinity of the ship, is currently on LHA big-deck amphibious assault ships, LSD Dock Landing Ships, LPD Amphibious Transport Docks, LHD amphibious assault ships and aircraft carriers including the first Ford-class carrier — the USS Ford (CVN 78).

The RAM is designed to function as part of a layered ship defense system by working in tandem with other defense systems.

For instance, the RF seeker built into the RAM can identify and zero in on radio signals coming from the seeker of a cruise missile.

“It uses not only an IR (infrared) imager or seeker but you also have the RF because many of the cruise missiles will be trying to use some sort of seeker to come after the ship. It is a passive RF receiver and the threat is broadcasting an RF signal to find the ship. The RAM will pick up on that radiated radar signature and hone on it,” said Brent Holtzen, RAM program official with Raytheon.

At the same time, cruise missile emit heat as well – so the RAM’s IR seeker can find them also,
