    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.

    Estonia eyes mid-range air defense systems to rectify NATO ‘oversight’

    By: Aaron Mehta WASHINGTON — Estonia's military is prioritizing the purchase of a midrange air defense system as the country seeks to plug a capability gap its defense minister called the result of a “total oversight” by NATO. During a Washington trip to attend Sen. John McCain's funeral, Estonian Defence Minister Jüri Luik told Defense News that NATO made a strategic mistake in the years following the collapse of the Soviet Union by not building up air defense capabilities, outside of rotational deployments of aircraft. “For a long time, there was no consideration that you would actively have to close the airspace at some point. So NATO countries have very weak air defense capabilities,” Luik said. “I think this is one of the priority systems, or priority areas, which every [one of the allied] countries should develop.” “I have to say with sadness that very few NATO countries actually have proper air defense capabilities. That is one of the areas which was gravely mismanaged, or was not under any attention,” he added. “I think that was a total oversight. But, of course, it was based on the idea that the era of big power tensions is over.” Luik hopes to put Estonia's money where his mouth is. The country in June signed an agreementwith MBDA to purchase more Mistral short-range air defense weapons, but has its eyes on adding another layer of protection. The country is looking at procuring a medium-range air defense system, similar to the Kongsberg network-centric air defence system, or NASAMS, purchased by Lithuania, which is also in use by Finland. While not declaring Estonia would also go after NASAMS, Luik acknowledged that regional air defense systems “should be as close as possible coordinated” with neighborhood countries. However, such a system is “the only step which is even theoretically available to our country with our defense spending,” Luik said, even if the upcoming March elections lead to a government willing to increase defense spending to about 2.5 percent of gross domestic product. (At the worst, Luik predicts, defense spending would remain flat.)
