The Marine Corps wants to protect its Hornets from GPS jammers
By: Shawn Snow
The Corps is looking to install antennas in its F/A-18 C/D Hornets to help the aircraft defeat GPS jammers.
In a request for information posted in early June by Naval Air Systems Command, or NAVAIR, the Corps wants to install the anti-jam antennas known as the Air Navigation Warfare Program, or NAVWAR, in 120 of the legacy Hornets.
The anti-jamming antenna “provides Global Positioning System (GPS) protection for Naval Air platforms by allowing for continued access to GPS through the use of Anti-Jam (AJ) Antenna Systems designed to counter GPS Electronic Warfare threats from intentional and unintentional interference,” Michael Land, a spokesman for NAVAIR, told Marine Corps Times in an emailed statement Tuesday.
The development comes as U.S. aircraft have faced mounting electronic warfare attacks against aircraft in Syria.
Army Gen. Tony Thomas, the commander of U.S. Special Operations Command, told audience members at a conference in April that adversaries were trying to bring down AC-130 gunships in Syria using electronic warfare, or EW.
“Right now in Syria, we're in the most aggressive EW environment on the planet, from our adversaries,” Thomas said. “They're testing us every day, knocking our communications down, disabling our AC-130s, et cetera.”
The Corps is amid an overhaul of its forces and equipment to prepare for a potential fight with near-peer adversaries like Russia and China.
Both countries boast an impressive array of electronic warfare capabilities. Russia has been using the Syrian battlefield to hone its EW skills.
The top Marine has oft repeated the threats posed to GPS systems from rising adversaries and says the Corps needs to be prepared to fight in GPS denied environments.
The F/A-18 is the Corps' bridging aircraft as it moves to the new high-tech F-35. As the Corps transitions the older legacy Hornets are undergoing a service life extension, meaning the aircraft are being updated to handle the modern battlefield.
“Installation in F/A-18 A-D helps ensure continued mission capability as the service life of the aircraft is extended and facilitates supportability by using more common equipment,” Land said.
The Navy and the Marine Corps already use the anti-jamming GPS antenna in a number of airframes, according to Land.
“Typical installations replace a platform's existing GPS antenna with a NAVWAR antenna and separate antenna electronics, while leaving a platform's GPS receiver in place,” Land added.
The Corps expects the F/A-18 to be in sunset by 2030.
As the Corps moves to the F-35 and phases out its Hornets, the legacy fighters will consolidate on the West Coast by 2018 with the exception of VMFA (AW)‐242, which will remain aboard the Corps' air station at Iwakuni, Japan until it transitions to the F-35 in 2028, according to the Corp's 2018 aviation plan.

DoD Stands Up New Biotech Manufacturing Center: Griffin
WASHINGTON: DoD is opening a new manufacturing innovation center dedicated to biotechnology to figure out how to replicate “nature's manufacturing plant” on an industrial scale, Pentagon research and engineering head Mike Griffin says. This is “a key new initiative,” Griffin stressed. The idea, he said at the annual McAleese conference, is “to learn how to do in an industrial way what nature has done for us in so many areas of things that we harvest and mine and use ... now that we are beginning to learn how to manipulate genomes.” Such technology could lead to DoD creating its own fuel using synthetic biology methods, for example. This would be a leap beyond ongoing efforts by DARPA that Sydney has widely reported, designed to protect soldiers against an enemy's biotech weapons. “This is a nascent technical area in the world, and especially in the United States,” Griffin told the audience here. “We want the national security community to be out in front on this.” The new center will be the ninth so-called ManTech center, designed to help overcome the so-called ‘valley of death' between research and commercialization by reducing risks. It will be the second ManTech center with a biotech focus: The first, BioFabUSA in New Hampshire, opened in 2016 to develop next-generation manufacturing techniques for repairing and replacing cells and tissues, which for example could lead to the ability to make new skin for wounded soldiers. Griffin elaborated on several other key areas for his two-year old office. DARPA is investing $459 million in the 2021 budget for AI Next, a “campaign” aimed at automating critical DoD business processes; improving the reliability of Artificial Intelligence systems; and enhancing the security of AI and machine learning tech. Griffin said his office is also “working with the Joint Artificial Intelligence Center (JAIC) under the CIO to bring about what we're calling AI Now: what can we do with AI that can get into the field and bring value to the national security community today, and the next day.” On 5G newtorks, he said that his deputy Lisa Porter is in charge of efforts to “figure out how we can use 5G to press our military advantage” and to protect US military networks. DoD launched that effort in 2019, with a $53 million reprogramming, he said. Congress added $200 million in the 2020 appropriations act, he added, and DoD is asking for $484 million in the 2021 budget. A key to future 5G networks and communications will be spectrum sharing, Griffin stressed. “There is no green field spectrum left,” he said, so DoD will have to figure out how to share spectrum to keep up with both its own demand and deal with pressure from commercial industry for it to give up spectrum. https://breakingdefense.com/2020/03/dod-stands-up-new-biotech-manufacturing-center-griffin

Air Force going ‘line by line’ to bring down nuclear missile costs
The Air Force "neglected" the complexity of the LGM-35A Sentinel's ground infrastructure, officials said, and is now looking to bring down costs.
