FARNBOROUGH, England, July 22 (Reuters) - U.S. Senator

Jerry Moran is urging the CEOs of major defense companies to

ensure that work performed by Spirit AeroSystems ( SPR ) will not be

disrupted by Boeing's ( BA ) planned acquisition of the

Kansas-based supplier.

Moran, a Kansas Republican who is the ranking member of the

Senate Commerce aviation subcommittee, told Reuters he had

spoken to the CEOS of Lockheed Martin ( LMT ), Northrop Grumman ( NOC ), Airbus

, General Atomics and Textron ( TXT ) over safeguarding future

defense work at the aero-structures giant.

"I want to make certain that the work continues in Kansas,"

Moran said, adding he wants to "make sure that we do not do

anything in this acquisition that diminishes the capability of

meeting our defense needs."
