An internal reorganization at Honeywell [HON] Aerospace has put the company’s work on four management and operations contracts with the National Nuclear Security Administration (NNSA) under the management of single retired Air Force colonel.

The company’s aerospace segment in July put David “DJ” Johnson — a Honeywell man since retiring from a 23-year Air Force career in 2007 — in charge of the newly created Honeywell Federal Solutions business, which reports to Steve Slijepcevic, president of the aerospace segment’s Mechanical Systems & Components business.

As vice president of Federal Solutions, Johnson is the point man for Honeywell’s management and operations contracts for the NNSA’s Kansas City National Security Complex in Kansas City, Mo.; Sandia National Laboratories in Albuquerque, N.M.; Nevada National Security Site near Las Vegas; and Savannah River Site in Aiken, S.C.

Honeywell wanted to streamline management of its NNSA business, a spokesperson said Monday. Before creating Federal Solutions, the company had separate managers for each of the NNSA sites on which it works, all of whom reported to Slijepcevic.

Wholly owned Honeywell subsidiaries Honeywell Federal Manufacturing & Technologies and National Technology and Engineering Solutions of Sandia manage the Kansas City plant and the Sandia National Laboratories, respectively. Honeywell is a partner on Nevada site manager Mission Support and Test Services and on Savannah River Site manager Savannah River Nuclear Solutions.

During his Air Force career, Johnson worked mostly on space systems and programs, according to his LinkedIn page. He continued work on space systems at Honeywell Aerospace, where he also managed the segment’s aircraft engine components business.
