The United States Air Force fiscal 2021 budget request includes $120 million for the Lockheed Martin U-2 reconnaissance aircraft, including about $48 million for the "high altitude, deep look" Advanced Synthetic Aperture Radar System-2B (ASARS-2B), $62 million for other upgrades, and nearly $10 million in overseas contingency operations funding. Raytheon builds ASARS-2B.
The $120 million Air Force request is $62 million more than appropriated last year, when ASARS-2B funds were not included.
The ASARS-2B program "replaces the front end components of the [Raytheon] ASARS-2A airborne radar to alleviate reduction in current ASARS-2A capability starting in FY21 [fiscal 2021] due to significant diminishing manufacturing sources and material shortages (DMSMS) issues," according to the Air Force fiscal 2021 budget request.
"ASARS-2B fixes these front end DMSMS issues while advancing the AF high altitude long range ISR radar capabilities," the request said. "ASARS-2B incorporates a new Active Electronically Scanned Array (AESA) antenna, Power Conditioning Unit (PCU), and Liquid Cooling System (LCS) while replacing the existing ASARS-2A Receiver Exciter Controller (REC) and radar data processing software on the Onboard Processor (OBP). The front-end (AESA, PCU, and LCS) together with the replaced/modified components (REC and OBP) significantly improve existing Synthetic Aperture Radar (SAR) and Ground Moving Target Indicator (GMTI) capabilities while adding new maritime capabilities. These efforts will align with back end up grades, previously referred to as ASARS-2C."
The Air Force said that it expects to award an ASARS-2B production contract by October next year and that the initial operational capability of ASARS-2B will come by fiscal 2023.
The ASARS-2B radar includes an open systems architecture and the radar's range is nearly double that of the previous ASARS-2A radar, Raytheon has said. ASARS-2B is to complement the Collins Aerospace Senior Year Electro-Optical Reconnaissance System (SYERS) multispectral imaging sensor.
On Feb. 18, Lockheed Martin and Collins Aerospace said that they had recently completed flight testing and deployment of SYERS-2C, a 10-band, high spatial resolution sensor.
"Developed with open mission systems standards to enable command, control and data exchange with 5th generation platforms, the sensor has become a critical asset to theater commanders bringing unique advantages to joint operations across the battlespace," the companies said.

Mark Pomerleau In 2018, the Department of Defense began following a new philosophy for cyber operations to better protect U.S. networks and infrastructure. Known as “defend forward,” the approach allows U.S. cyber forces to be active in foreign network outside the United States to either act against adversaries or warn allies of impending cyber activity that they've observed on foreign networks. After the U.S. military killed an Iranian general in a Jan. 2 drone strike and after national security experts said they expect Iran might take some retaliatory action through cyber operations, the specter of increased cyber attacks against U.S. networks puts Cyber Command and its new approach front and center. “This Iran situation today is a big test of the ‘defend forward' approach of this administration,” James Miller, senior fellow at Johns Hopkins Applied Physics Laboratory and former undersecretary of defense for policy, said at a Jan. 7 event hosted by the Council on Foreign Relations. “Will [Cyber Command] take preventative action? Will they do it in a way that our allies and partners support and that can be explained to the public?” While Iran fired several missiles Jan. 7 at a base in Iraq where U.S. troops lived as an initial response to the drone strike, many national security experts expect Iran could continue cyber actions as further retaliation for the strike. Iran could also ratchet up its cyber operations in the United States following the collapse of portions of the 2015 nuclear deal between the United States, Iran and five other nations to curb Iran's nuclear weapons capability in return for sanctions relief. Over the past 12 months, the White House and Congress streamlined many of the authorities used to conduct cyber operations to help cyber forces to get ahead of threats in networks around the world. One such provision in last year's annual defense policy bill provides the Pentagon with the authority to act in foreign networks if Iran, among other named nations, is conducting active, systematic and ongoing campaigns of attacks against the U.S. government or people. Cyber Command declined to comment on what, if anything, they were doing differently since the drone strike. Some experts, however, have expressed caution when assessing how well this defend forward approach has worked thus far given it is still relatively new. “The jury is very much still out here,” Ben Buchanan, assistant professor and senor faculty fellow at Georgetown University, said at the same event. “We don't have a lot of data, there's been a lot of hand-wringing ... about these authorities and about how Cyber Command may or may not be using them. I just don't think we've seen enough to judge whether or not ... [it is] meaningfully changing adversary behavior.” Others have also expressed reservations about how effective Iran can even be in cyberspace toward U.S. networks. “Iran is a capable cyber actor, Iran is a wiling cyber actor. That means Iran will conduct cyberattacks,” said Jacquelyn Schneider, Hoover fellow at the Hoover Institution at Stanford University. “It's not like they have this capability and they've been deterred in the past and maybe now they're going to turn it on. I think they've been trying this entire time.” Complicating matters further could be other actors trying to take advantage of U.S.-Iran imbroglio for their own interests. Priscilla Moriuchi, senior principal researcher and head of nation-state research at threat intelligence firm Recorded Future, said over the past several months, there have been reports of Russian state-affiliated actors hijacking Iranian cyber infrastructure to conduct operations masquerading as Iranians. “That creates its own uncertainty,” she said at the same event. “Another level of potential what we call inadvertent escalation if a country perceives that they are attacked by Iran but in reality, it” wasn't. https://www.fifthdomain.com/dod/2020/01/09/how-tensions-with-iran-could-test-a-new-cyber-strategy/
