Defense contractor BAE Systems won a $146 million contract for work on the USS Gettysburg, part of a class of guided-missile cruisers whose weapons and computer systems are undergoing upgrades to ensure they reach their 35-year service life.
Work on the Gettysburg, which will be performed at London-based BAE's shipyard in Norfolk, Va., is scheduled for completion by 2020, and includes maintenance, modernization and repair, the U.S. Department of Defense said in a statement on Monday. The contract includes options that could bring its total value to $151.3 million.
Built by Bath Iron Works, Gettysburg was commissioned in 1991 under former President George H.W. Bush. It belongs to the Ticonderoga class, which was first deployed in 1983 and uses Aegis technology to track aerial targets. Carrying Tomahawk missiles, the vessels can support carrier strike groups as well as conduct independent operations.
The modernization program for the cruisers includes updates to computer and display equipment as well as electrical and mechanical systems. Weapons and sensor sets will be modified to improve submarine-combat capabilities, the Navy said, and electro-optical systems will be added that can monitor the ship's surroundings without radar emissions.

Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above – five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat. To address this thermal challenge, DARPA recently announced its Materials Architectures and Characterization for Hypersonics (MACH) program. The MACH program seeks to develop and demonstrate new design and material solutions for sharp, shape-stable, cooled leading edges for hypersonic vehicles. A Proposers Day describing the program will take place January 22, 2019 in Arlington, Virginia: https://go.usa.gov/xEcEy. “For decades people have studied cooling the hot leading edges of hypersonic vehicles but haven't been able to demonstrate practical concepts in flight,” said Bill Carter, program manager in DARPA's Defense Sciences Office. “The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we've seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance.” The MACH program will comprise two technical areas. The first area aims to develop and mature fully integrated passive thermal management system to cool leading edges based on scalable net-shape manufacturing and advanced thermal design. The second technical area will focus on next-generation hypersonic materials research, applying modern high-fidelity computation capabilities to develop new passive and active thermal management concepts, coatings and materials for future cooled hypersonic leading edge applications. Both technical areas will be described in a Broad Agency Announcement solicitation expected in mid-January 2019 on DARPA's FedBizOpps page here: http://go.usa.gov/Dom. The MACH program seeks expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems.
