Northrop Grumman Builds Very Lightweight Torpedo for US Navy

By Fernando Catta-Preta May 21, 2020 - Northrop Grumman has successfully manufactured and tested the first industry-built Very Lightweight Torpedo (VLWT) for the U.S. Navy.

The prototype torpedo is based on the Pennsylvania State University Applied Research Laboratory's (PSU-ARL) design that was distributed to defense industrial manufacturers in 2016. Northrop Grumman, which independently funded the research and development, will offer the design-for-affordability improvements to this VLWT as Northrop Grumman's response for the Navy's Compact Rapid Attack Weapon program.

Northrop Grumman‘s torpedo design and production legacy reaches back over 80 years to World War II through its Westinghouse acquisition. In 1943, Westinghouse won the Navy contract to reverse engineer a captured German electric torpedo and in 12 months began producing the MK18 electric torpedo, which turned the tide of the undersea warfare in the Pacific. Northrop Grumman has been at the forefront of torpedo design and production ever since, to include the current MK48 Common Broadband Advanced Sonar System (CBASS) heavyweight torpedo and MK50 Lightweight Torpedo.

Today, Northrop Grumman is the only company in full rate production of MK54 and MK48 torpedo nose arrays and has delivered over 600 MK54 arrays and over 70 MK48 arrays to the U.S. Navy.

Applying its engineering and manufacturing expertise, Northrop Grumman improved upon the VLWT baseline design to replace high-cost components and drive overall affordability, reproducibility and reliability. Those altered sections were built and tested using PSU-ARL's own test equipment for confidence.

“The successful testing of the torpedo nose on the first try is a testament to Northrop Grumman's design-for-affordability approach, which will significantly reduce cost without sacrificing operational performance,” said David Portner, lead torpedo program manager, undersea systems, Northrop Grumman.

Northrop Grumman assembled the prototype VLWT using a Stored Chemical Energy Propulsion System (SCEPS) manufactured by teammate Barber-Nichols, Inc., (BNI) of Denver, Colorado.

“The nation needs advanced undersea warfare capabilities now more than ever," said Alan Lytle, vice president, undersea systems, Northrop Grumman. “We are ready to support fielding the VLWT which will increase subsea lethality and enable innovative concepts of operations for multiple warfighting platforms.”

Northrop Grumman's manufacturing plan would span the country by building components in California, Utah, Minnesota, Colorado, West Virginia and Maryland.

    In first, MDA remotely launches a missile

    By: Jen Judson WASHINGTON — The first-ever test of the Terminal High Altitude Area Defense system'sability to remotely fire an interceptor was deemed a success by the U.S. Missile Defense Agency. Following the test in the early hours of Aug. 30, the Lockheed Martin-made THAAD has now had 16 successful intercept tests in a row. But the significant milestone is proving the ability to remotely engage the system with a government-developed remote launcher kit. The capability provides extended range of a defended area, an MDA statement notes. “Preliminary indications are that planned flight test objectives were achieved and the target was successfully intercepted by the THAAD weapon system,” the statement reads. "This test demonstrates the expanding capabilities of the THAAD weapon system and its ability to intercept and destroy ballistic missile threats in defense of our nation, deployed forces and allies,” MDA Director Vice Adm. Jon Hill said in the statement. THAAD operators from the E-62 Battery conducted radar operations as well as launcher and fire control operations employing a procedure used in combat and were unaware of the target-launch timing. The ability to launch an interceptor remotely achieves a more layered — and ultimately less stove-piped — approach to regional ballistic missile defense and to increase the battlespace. The U.S. Army is also working to integrate the Patriot medium-range air-and-missile defense system with THAAD in response to an urgent operational need on the Korean Peninsula. That effort uses some of the same principles of decoupling launchers and radars so an operator can, for instance, use a THAAD radar (which can see farther than a Raytheon-made Patriot radar) but decide to engage a Patriot interceptor depending on the threat picture. The ability to use the THAAD radar also gets more out of the Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3 MSE) missile fired from Patriot units, which outperforms the organic Patriot radar. Earlier, in an Aug. 29 Army test also at White Sands Missile Range, a PAC-3 Cost Reduction Initiative interceptor took out an air-breathing threat “at a record distance," according to a Lockheed Martin statement. The company builds the missile as well as the PAC-3 MSE. The test also showed it can be integrated into the Northrop Grumman-made Integrated Air and Missile Defense Battle Command System, the command-and-control system of the Army's future air and missile defense architecture. The test demonstrated the Northrop system's ability to detect, track and engage a low-flying threat at a distance that exceeds the range of the current Patriot system, according to a Northrop Grumman statement. https://www.defensenews.com/land/2019/08/30/first-remotely-launched-terminal-missile-defense-test-deemed-a-success

    L’annonce d’un réarmement massif en Europe est-elle un tournant pour l’industrie française ?

    L'Express détaille dans un dossier les perspectives stratégiques pour l'industrie française face aux réarmements en Europe et à la suite d'un rapport parlementaire sur l'état de nos forces armées face à une guerre de haute intensité à horizon 2030. L'idée est d'envisager un budget à la hauteur, le nombre des avions de combat (dans l'Armée de l'Air et de l'Espace et la Marine) étant passé par exemple, de 686 en 1991 à 254 unités en 2021. Si la loi de programmation militaire engage 295 Md€ sur sept ans, la marche reste haute face au conflit en Ukraine. Comme le rappelle le Président-directeur général de Dassault Aviation, Eric Trappier, « La guerre en Europe est un choc. La menace est à nos portes. Il faut réagir vite. C'est la fin des dividendes de la paix ». Suivant l'exemple français, l'Allemagne et la Suède amorcent un réarmement, comme en témoigne le nouvel investissement de 100 Md€ allemand dans sa défense. Le défi pour le secteur industriel est grand, Eric Trappier appelle « l'actionnariat privé à rentrer dans les activités de défense puisque l'Etat ne peut pas tout », comme il l'a martelé fin mars face aux parlementaires. Le danger reste la vulnérabilité de la chaîne de sous-traitance et le risque de perte en compétence, alors que les cycles de fabrication sont longs. « Pour être prêt dans un an, il faut démarrer maintenant", presse Marc Darmon, Directeur général adjoint de Thales.

    The US Army’s three focus areas to avoid protracted combat

    By: Aaron Mehta WASHINGTON — As the U.S. Army's Multi-Domain Operations concept continues to evolve and be tested, the service is finding three key areas to focus on ahead of any major conflict. Lt. Gen. Eric Wesley, the head of the Army Capabilities Integration Center, told reporters Dec. 9 that as his office continues to experiment with the MDO concept and war game it out, a focus on the “competition space” — the time before a conflict breaks out between two sides — will put the Army in a strong position to dictate the flow of how a conflict will play out. “Leveraging the competition space, we found, is the most important aspect of getting the conflict portion right. That's something that we have to expand our capabilities in, and we're not completely postured to do right now,” Wesley said. The first focus area is on countering information warfare and unconventional warfare, Wesley said, in what will not come as a surprise to those who have paid attention to what Russia has done in recent years. The second area of focus Wesley calls “conducting the intelligence preparation of the battlefield.” At its core, this involves studying the enemy order of battle and understanding how a conflict may flow. And if that seems like a classic tenet of combat to you, Wesley wouldn't disagree. “That's something we used to do all the time in western Europe in the 1980s, and since we've withdrawn from the continent, we don't do that to the degree we used to,” he said. “Plus, there are aspects to doing that, which are virtual, that we didn't do in the ‘80s that we have to do now.” The third aspect is about posturing your forces to be agile enough to quickly enter a conflict if needed. Doing so, Wesley believes, “precludes protracted conflict. If you can transition rapidly and force your opponent to recalculate, that can preclude the need for protracted conflict.” Wesley's team has had a busy year, developing and testing their ideas while publishing MDO 1.5 and switching from being under Training and Doctrine Command to the Army's new Futures Command. Despite that move on the organizational chart, ARCIC has stayed at Fort Eustis, Virginia, and remains geolocated with TRADOC, which has helped mitigate unnecessary duplication of overhead. By having TRADOC continue to manage basic administrative issues such as personnel, travel and orders assistance, ARCIC is able to focus on using its limited staffing where it's most needed. As part of the move to Futures Command, ARCIC is in the process of standing up three new groups: an internal Red Team, an Operational Environment section, and a 3/5/7 office modeled on the service's operations and planning general staff position. “We're not just moving deck chairs,” Wesley said. “Instead, we're also having to evolve our culture and change our organization so that its sufficiently nested” within Futures Command. Asked if he was worried about people in ARCIC having too many bosses, Wesley waved those concerns away as unrealistic. Sometimes “having one boss is a luxury that is impractical. And particularly when you're talking about [the need to] modernize across the entire enterprise — not just material modernization but doctrine, organization, training, leader development, policy, facilities, personnel,” he said. “So those dotted lines are healthy because they force integration, which is indispensable to do this concept.” https://www.defensenews.com/land/2019/01/09/the-armys-three-focus-areas-to-avoid-protracted-combat/
