LRASM Completes 3rd Successful Flight Test

 

ORLANDO, Fla., Feb. 19, 2015by Lockheed Martin

 

 

The Long Range Anti-Ship Missile (LRASM) built by Lockheed Martin achieved a third successful air-launched flight test, with the missile performing as expected during low altitude flight.

The test, conducted on Feb. 4, was in support of the Defense Advanced Research Projects Agency (DARPA), U.S. Air Force and U.S. Navy joint-service LRASM program.   

Flying over the Sea Range at Point Mugu, California, a U.S. Air Force B-1B bomber from the 337th Test and Evaluation Squadron at Dyess Air Force Base, Texas, released the LRASM prototype, which navigated through planned waypoints receiving in-flight targeting updates from the weapon data link.

“LRASM continues to prove its maturity and capabilities in this flight test program,” said Mike Fleming, LRASM air launch program director at Lockheed Martin Missiles and Fire Control. “This much-needed weapon seeks to provide a new capability that would enable deep strike in previously denied battle environments.”

LRASM is a precision-guided anti-ship standoff missile leveraging the successful Joint Air-to-Surface Standoff Missile Extended Range (JASSM-ER) heritage, and is designed to meet the needs of U.S. Navy and Air Force warfighters in a robust anti-access/area-denial threat environment. JASSM-ER, which recently completed its operational test program, provides a significant number of parts and assembly-process synergies with LRASM, resulting in cost savings for the U.S. Navy and Air Force Offensive Anti-Surface Warfare programs.

The tactically representative LRASM is built on the same award-winning production line in Pike County, Alabama, as JASSM-ER, demonstrating manufacturing and technology readiness levels sufficient to enter the engineering, manufacturing and development phase and to meet urgent operational needs.

Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 112,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s net sales for 2014 were $45.6 billion.

DARPA Works On New Anti-Ship Missile

 

November 14, 2013 by Richard Sisk - defensetech.org

 

The Defense Department’s top research agency has focused on developing a program to make sure that the Navy is not “outsticked” by China as U.S. forces re-balance to the Pacific.

 

“We’re looking at a long-range anti-ship missile” to counter China’s development of its own long-range strike assets, said Dr. Arati Prabhakar, director of the Defense Advanced Research Projects Agency. “We’re concerned about being ‘out-sticked’” in what has been dubbed the “Pacific pivot” of troops and ships following the wars in Iraq and Afghanistan, Prabhakar said.

 

Prabhakar spoke at the opening of an all-day forum on military issues sponsored by the Defense One website.

 

DARPA Works On New Anti-Ship Missile

China’s development of the DF-21D ASBM (Anti-Ship Ballistic Missile), technically a cruise missile dubbed the “carrier killer,” has raised alarms on Capitol Hill. “We are technically ‘out-sticked’ by Chinese anti-ship cruise missiles (ASCM) right now,” Rep. Randy Forbes, R-Va., head of the Readiness Subcommittee of the House Armed Services Committee.

 

Forbes told the RealClearDefense website last week that that the Navy’s main anti-ship missile, the Harpoon, “does not have the range or survivability” to match the threat from the Chinese Navy.

 

However, the non-partisan Congressional Research Service last spring reported that the threat from the Chinese anti-ship missiles was not quite the “game changer” that some defense analysts had feared.

 

The Navy and the Air Force could counter by “employing a combination of active and passive measures” against the Chinese missiles, the CRS said in a report. One of the methods suggested by the CRS to defeat the Chinese system would be to equip Navy ships with electronic warfare systems that could generate radar “smoke clouds” to confuse the terminal guidance systems of the Chinese missiles.

 

In August, DARPA and the Office of Naval Research conducted the first flight of a prototype in the Long Range Anti-Ship Missile (LRASM) program, which is meant to develop a weapon that can hit enemy ships out of the range of a counter-strike.

 

A B-1 bomber from the 337th Test and Evaluation Squadron conducted the mission from Dyess Air Force Base, Tex., to the Point Mugu Sea Test Range off the coast of southern California and successfully hit a moving target, DARPA said. Halfway to the target, the missile switched to its autonomous guidance system, which completed the mission, DARPA said.

 

“This fully functional test is a significant step in providing the U.S. Navy and U.S. Air Force with a next-generation anti-ship missile capability,” Artie Mabbett, the DARPA program manager for the LRASM, said after the test.

 

At the Defense One forum, Prabhakar said the autonomous guidance system for the LRASM was vital vital to counter an enemy’s potential ability to jam Global Positioning Satellite guidance.

 

Prabhakar also noted DARPA’s difficulty in doing work on space systems in an era of cost-cutting and declining budgets.

 

Space “is a place where cost is just an overwhelming issue,” Prabhakar said. “It’s so hard, it takes so long to do anything in space. Even the smallest satellite costs tens of millions of dollars,” she said.

 

The budget cuts also put the future of defense research at risk, Prahhakar said. Unless Congress lifts the sequester cuts that will take about $500 billion out of defense spending over the next 10 years, “we’re going to have a future of power point (presentations) and not real systems,” she said. “We want to do things that really get built.”

Darpa Tests LRASM Anti-Ship Missile Prototype

Sept. 09, 2013 defense-aerospace.com

Anti-Ship Missile Prototype Successfully Conducts First Solo Test Flight

 

Adversaries’ sophisticated air defense systems can make it difficult for current air- and surface-launched anti-ship missiles to hit their targets at long range. To engage specific enemy warships from beyond the reach of counter-fire systems, warfighters may require launching multiple missiles or employing overhead targeting assets such as radar-equipped planes or Global Positioning System (GPS) satellites—resources that may not always be available.

 

To help address these challenges, the Defense Advanced Research Projects Agency (DARPA) and the Office of Naval Research (ONR) are collaborating on the Long Range Anti-Ship Missile (LRASM) program, which successfully launched its first prototype on August 27.

 

Designed for both surface and air launch, LRASM seeks to develop an autonomous, precision-guided anti-ship standoff missile based on the successful Joint Air to Surface Standoff Missile Extended Range (JASSM-ER) system. LRASM aims to incorporate sensors and systems to create a stealthy and survivable subsonic cruise missile with reduced dependence on intelligence, surveillance and reconnaissance (ISR) platforms, network links and GPS navigation in electronic warfare environments. The program also focuses on precision lethality in the face of advanced countermeasures.

 

“This fully functional test is a significant step in providing the U.S. Navy and U.S. Air Force with a next-generation anti-ship missile capability,” said Artie Mabbett, DARPA program manager for LRASM. “This test is the culmination of the five-year development and integration of advanced sensors in an All-Up-Round (AUR) missile. It also represents the first time we’ve integrated advanced sensors and demonstrated the entire system, resulting in performance that substantially exceeds our current capabilities.”

 

DARPA designed the free-flight transition test (FFTT) demonstration to verify the missile’s flight characteristics and assess subsystem and sensor performance. Beyond the primary objectives of the free-flight transition, the test vehicle also detected, engaged and hit an unmanned 260-foot Mobile Ship Target (MST) with an inert warhead.

 

A B-1 bomber from the 337th Test and Evaluation Squadron conducted the mission from Dyess AFB, Tex., to the Point Mugu Sea Test Range off the coast of southern California. Once in position, the B-1 released the LRASM, which followed a pre-planned route towards the target. Approximately halfway to its destination, the weapon switched to autonomous guidance, in which it autonomously detected the moving MST and guided itself to hit the desired location on the target. A F/A-18 fighter from the Air Test and Evaluation Squadron (VX) 31 in China Lake, Calif., followed the weapon during the flight.

 

Lockheed Martin Missiles and Fire Control (LMMFC) is the prime contractor for the demonstration of the LRASM weapon. BAE Systems’ Information and Electronic Systems Integration division is the prime contractor for the design and delivery of LRASM’s onboard sensor systems.

LM Completes Captive Carry Tests with LRASM, Future USAF and Navy Missile

Jul 12, 2013 ASDNews Source : Lockheed Martin Corporation

 

Lockheed Martin [NYSE: LMT] recently completed a series of Long Range Anti-Ship Missile (LRASM) captive carry flight tests at the Sea Range in Point Mugu, Calif., advancing the research program toward its first missile release and free flight test later this year.

 

The captive carry missions were flown aboard a U.S. Air Force B-1B from the 337th Test and Evaluation Squadron at Dyess Air Force Base, Texas. The primary mission objectives were to collect telemetry for post-flight analysis, verify proper control room telemetry displays and simulate all the test activities that will occur in later air-launched flight tests. All test objectives were met.

 

“Collecting telemetry data while flying in the B-1B bomb bay significantly reduces risk ahead of the first launch,” said Mike Fleming, LRASM air launch program manager at Lockheed Martin Missiles and Fire Control. “Initial assessments indicate the missile performed as expected.”

 

The LRASM program is in development with the Defense Advanced Research Project Agency (DARPA) and the Office of Naval Research. After a competition in 2009, Lockheed Martin’s LRASM was selected to demonstrate air- and surface-launched capability to defeat emerging sea-based threats at significant standoff ranges.

 

LRASM is an autonomous, precision-guided anti-ship standoff missile leveraging the successful Joint Air-to-Surface Standoff Missile Extended Range (JASSM-ER) heritage, and is designed to meet the needs of U.S. Navy and Air Force warfighters in a robust anti-access/area-denial threat environment.

 

Armed with a proven 1,000-lb. penetrator and blast-fragmentation warhead, LRASM employs a multi-mode sensor, weapon data link and an enhanced digital anti-jam Global Positioning System to detect and destroy specific targets within a group of ships.
