Aerojet Welcomes Michael Bright to Aerojet as Vice President of its Missile Defense Business Unit

SACRAMENTO, Calif., April 25, 2011 – Aerojet, a GenCorp (NYSE: GY) company, announced today that Michael (Mike) Bright has joined the corporation as vice president of the Missile Defense Business Unit.

Bright comes to Aerojet from Lockheed Martin with a long history in the missile defense community. His very successful engineering, program management and product line management career make him an ideal fit for this leadership position. Bright has a Bachelor of Science degree in Physics from Fort Lewis College and has completed master’s-level courses in Aerospace and Systems Engineering, Leadership, Program Management and Financial Strategies. He has received numerous prestigious awards which attest to his outstanding performance, management and leadership abilities.

Bright replaces Pete Massey, the current Missile Defense Business Unit leader, who will be leaving his position to join the company’s Business Development and Strategy department. Massey has successfully led the Missile Defense team for the past 10 months and has been instrumental in overseeing the business unit’s excellent growth and profitability efforts. His leadership has positioned us to both capture and retain critical program revenue. In his new role, Massey will enhance and expand Aerojet’s external business relationships throughout the national and international marketplaces.

The addition of the OMS engine will be a wonderful opportunity for our new SPACE CAMP trainees to learn more about on-orbit propulsion.”
