Museum by 2022. Universal Payload Adapter and new payloads In January 2014, President Obama signed a budget that included a $10 million study on adapting the U-2's superior sensors for the RQ-4. In April 2015, Northrop Grumman reportedly installed the U-2's Optical Bar Camera (OBC) and Senior Year Electro-Optical Reconnaissance System (SYERS-2B/C) sensors onto the RQ-4 using a Universal Payload Adapter (UPA). Successful testing indicated that all RQ-4s could be similarly retrofitted. On 14 July 2015, Northrop Grumman and the USAF signed an agreement to demonstrate an RQ-4B fitted with the U-2's OBC and SYERS-2C sensors. Two Global Hawks are to be fitted with the UPA, involving the installation of 17 payload adapter fixtures and a new payload bay cover, as well as software and mission system changes for each sensor. The UPA can support of sensors and will create a canoe-shaped sensor bay on the fuselage's underside. Northrop Grumman also expects to receive a contract to integrate the UTC Aerospace Systems MS-177 multispectral sensor used on the Northrop Grumman E-8C JSTARS onto the RQ-4. The MS-177 will replace the SYERS-2 and includes modernized optronics and a gimbaled rotation device to increase field of view by 20 percent. The RQ-4B flew with the SYERS-2 on 18 February 2016. Raytheon developed the AN/ALR-89 self-protection suite consisting of the AN/AVR-3 laser warning receiver, AN/APR-49 radar warning receiver, and jamming system, along with the ALE-50 towed decoy for the Global Hawk. Range Hawk Although the Global Hawk is being retired from combat use, the Department of Defense's Test Resource Management Center (TRMC) is acquiring them to support the SkyRange program to test hypersonic missiles by 2024. Tests are currently monitored by ships, but it can take a ship 21 days to be positioned and outfitted for use, limiting flights to about a dozen airborne demonstrations a year. By using unmanned aircraft to track hypersonic systems, faster availability and deployment could support a test rate of up to one per week. To perform this new mission, the Global Hawk is retrofitted into the Range Hawk, which involves configuring it to look up rather than down by repositioning onboard avionics and installing new sensors and instrumentation suites to track an overhead hypersonic vehicle. The program will use four Block 20 and 20 Block 30 airframes retired from USAF service. Design Overview The Global Hawk UAV system comprises the RQ-4 air vehicle, which is outfitted with
