VANDENBERG AIR FORCE BASE, Calif. - The U.S. Air Force and Army
      successfully launched two Lockheed Martin rockets Saturday night within minutes of
      each other, but 4,200 miles apart, completing a test supporting the Ballistic Missile
      Defense Organization's (BMDO) National Missile Defense program. A
      Multi-Service Launch System (MSLS) rocket, launched by the Air Force, lifted off
      from Vandenberg Air Force Base, Calif., at 7:01 p.m. PDT carrying a suite of
      targets. A Payload Launch Vehicle (PLV), launched by the Army, lifted off from the
      Kwajalein test range in the South Pacific approximately 21 minutes later carrying an
      exoatmospheric kill vehicle that acquired, tracked and discriminated between the
      targets and then destroyed the primary target.

      The MSLS is a refurbished, three-stage Minuteman II intercontinental ballistic missile
      (ICBM) with a new front section. Lockheed Martin Astronautics designed and built
      the new front section and associated flight hardware for the MSLS and provides
      launch services under contract to the U.S. Air Force Test and Evaluation
      Directorate, Space & Missile Systems Center, Kirtland Air Force Base, New
      Mexico. All five MSLS flights have been successful. Lockheed Martin Missiles &
      Space is the prime contractor for the PLV which also is a refurbished, two-stage
      Minuteman II ICBM with a new front section. Today's MSLS mission successfully
      deployed two inert targets while the PLV delivered and deployed the
      exoatmospheric kill vehicle.

      "This fifth consecutive successful flight of the MSLS has demonstrated the reliability
      of this vehicle as well as Lockheed Martin's continuing commitment to mission
      success," said G. Thomas Marsh, Lockheed Martin Astronautics president. "Today's
      test provides the BMDO important information to be used in strengthening the
      defense of the United States. We are pleased to be a member of the team that
      worked together to make the mission a success."

      The MSLS is designed to launch a variety, or "multi-service" classes of missions,
      including ballistic experiments, like the one launched today, carrying payloads
      weighing up to 1,450 pounds as far as 4,200 miles downrange. This was the fifth
      MSLS launch. The first four were launched from Vandenberg Air Force Base, Calif.,
      on Sept. 27, 1996, January 16, 1997, June 23, 1997, and Jan. 15, 1998.

      Astronautics and Missiles & Space are two of the operating units of Lockheed
      Martin Space Systems headquartered in Bethesda, Md. Both companies design,
      develop, test and manufacture a variety of advanced technology systems for space
      and defense. Astronautics' chief products include interplanetary spacecraft and other
      space systems, space launch systems and ground systems. The chief products of
      Missiles & Space include fleet ballistic missiles, missile defense systems and
      spacecraft for commercial and government customers.

     Mission Background

The Minuteman weapon system was conceived in the late 1950s and deployed in the early 1960s. Minuteman was a
revolutionary concept and an extraordinary technical achievement. Both the missile and basing components incorporated
significant advances beyond the relatively slow-reacting, liquid-fueled, remotely-controlled intercontinental ballistic missiles of
the previous generation. From the beginning, Minuteman missiles have provided a quick-reacting, inertially guided, highly
survivable component to Americaís nuclear Triad. Minutemanís maintenance concept capitalizes on high reliability and a
"remove and replace" approach to achieve a near one-hundred percent alert rate.
Through state-of-the-art improvements, the Minuteman system has evolved to meet new challenges and assume new missions.
Modernization programs have resulted in new versions of the missile, expanded targeting options, significantly improved
accuracy, and survivability. Todayís Minuteman weapon system is the product of almost 35 years of continuous enhancement.
The current Minuteman force consists of 515 Minuteman IIIís located at F.E. Warren AFB, Wyo., Malmstrom AFB, Mont.,
Minot AFB, N.D., and Grand Forks AFB, N.D. The last round of base realignment and closing decisions has forced a
realignment of Minuteman missiles from Grand Forks, AFB toMalmstrom, AFB by September, 1998. Ratification of Start I
and the possible implementation of Start II, means that Minuteman III will become the only land-based ICBM in the TRIAD.
An extensive life extension program is underway to keep the remaining missiles safe, secure and reliable well into the 21st
Century. These major programs include: replacement of the aging guidance system, remanufacture of the solid-propellant
rocket motors, replacement of standby power systems, repair of launch facilities, and installation of updated, survivable
communications equipment and new command and control consoles to enhance immediate communications.
