Amentum, leading contractor for the Department of Energy and other government agencies, last week outlined management roles for a new National Security business group that the Maryland-based company is putting together under a corporate reshuffling by the new CEO.  

“Today, I am announcing the leaders of each of these three businesses [within National Security], as well as our business development organization leader,” Amentum’s Environment & Energy president Mark Whitney wrote in a Thursday memo. The memo spells out a new structure from new CEO John Heller

, who assumed the top job in late March.

Jim Blankenhorn will head up Environment & Security, including contracts for DoE, National Nuclear Security Administration, Department of Defense and related entities focusing on areas such as nuclear management remediation and project management, nonproliferation and countering weapons of mass destruction, according to the memo. Blankenhorn, with more than 30 years industry experience, is currently senior vice president for Amentum’s Technical Services business.

David Batters will still lead Amentum’s International business, including the United Kingdom Atomic Weapons Establishment and the UK Nuclear Decommissioning Authority, according to the memo. His prior roles included nine years as the Group CFO and main board director at the Nuclear Decommissioning Authority.

National Security business development will be led by Jeff Kerridge, current senior vice president, business development for Environment & Energy at Amentum, Whitney said in the memo. Kerridge oversees new business and teaming strategies internationally, and has 38 years of experience.

Laine Klein will lead the Intelligence section that combines intelligence community work from Amentum and PAE, which the company acquired in February. Klein has been with Amentum and its predecessor companies for nine years. She currently serves as senior vice president and sector lead, responsible for Amentum’s work for the intelligence sector, including security services and classified design and construction, according to the memo.
