  Small defense businesses see cash issues during coronavirus outbreak

  By: Aaron Mehta WASHINGTON — More than 60 percent of small companies in the defense supply chain are seeing disrupted cash flow, according to a new survey put forth from the National Defense Industrial Association. “This survey shows how the defense lifeline runs through small business,” Hawk Carlisle, NDIA's president and CEO, said in a statement. “These companies must survive if the defense industrial base is to remain the best in the world on other side of COVID-19.” COVID-19 is a newly discovered coronavirus — a family of viruses, some of which cause disease in people and animals, named for crownlike spikes on their surfaces. As of Friday, 458 small businesses had responded to the survey, which will remain open through April 10. Fifty-five percent of respondents have less than $5 million in annual revenue, and 70 percent have less than 50 employees. Sixty-two percent of the respondents have seen disrupted cash flow as a result of the economic downturn. Primarily, those have come as cuts to billable hours or delayed payments from prime contractors because of shutdowns or telework. A lack of telework options is also an issue for contractors. Notably, 54 percent of respondents say they cannot work on a contract because they are currently under a shelter-in-place order. And optimistically, 69 percent do not expect cost overruns on fixed-price contracts as a result of the coronavirus-related disruptions. Those that do expect such overruns predict them to be in the 10-20 percent range. The results of the survey were delivered Friday to Ellen Lord, the undersecretary of defense for acquisition and sustainment. Speaking to reporters on Wednesday, Lord said she is closely watching the lower tier of the supply chain for weak spots that may appear. Last week, the Defense Department announced new measures to increase progress payments out to both small and large companies to ensure they are able to keep work moving on schedule. https://www.defensenews.com/industry/2020/03/27/small-defense-businesses-seeing-cash-issues-during-coronavirus-outbreak-survey/

  Northrop Grumman gets a start on next-gen missile warning satellites

  By: Daniel Cebul WASHINGTON — The Air Force awarded Northrop Grumman a contract worth as much as $47 million for an analysis of system and payload requirements for a new missile warning satellite system in polar orbit. Specifically, the contract will be used for the Next Generation Overhead Persistent Infrared Polar (OPIR) space vehicles 1 and 2. Work will be performed in Redondo Beach, California, and is expected to be completed by June 25, 2020, according to a contract announcement. The OPIR polar space vehicles will be part of a five-satellite constellation that will augment the legacy Space-based Infrared Satellite (SBIRS), which operates as the U.S. military's early warning missile system. During the fiscal year 2019 budget release, the Air Force announced its plans to cancel the 7th and 8th SBIRS satellites in favor or reallocating funds towards OPIR systems. In May 2018, the Air Force released a notice of intent to sole-source contracts to Lockheed Martin and Northrop for the new program. Lockheed Martin will produce three geosynchronous orbiting satellites and Northrop Grumman is responsible for two polar orbiting satellites. The first geosynchronous OPIR satellite is scheduled to be launched in 2023, and the first polar satellite is scheduled to launch in 2027. The Air Force wants the entire “block O” architecture to be operational by FY 2029. Lockheed Martin is the prime contractor on the SBIRS satellites. Northrop Grumman provides the sensors, a scanner and a starer, on those satellites.
