## Description

INTRODUCTION The Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, MD intends to negotiate on a sole source basis with Fisica Applied Technologies, Inc. (CAGE: 1TS25) for the upgrade of the horizontal polarized High Altitude Electromagnetic Pulse System (HEMPS) to meet new MIL-STD testing environment requirements.

GENERAL INFORMATION The present day Horizontal Electromagnetic Pulse Systems (HEMPS) were developed and fielded between March 2008, and January 2011 at the Patuxent Naval Air Station and White Sands Missile Range. The systems utilize advanced pulsed power technologies to produce representative electromagnetic waveforms for the early time (E1) component of the High Altitude Electromagnetic Pulse (HEMP) environment as described in MIL-STD-2169C.

The systems are being upgraded to produce equivalent waveforms for MIL-STD-2169D. There are no commitments by the Government to issue any solicitations, make an award or awards, or to be responsible for any monies expended by any interested parties before award of a contract for the efforts mentioned above. Information provided herein is subject to change and in no way binds the Government to solicit for or award a contract. No telephone response will be accepted.

For more information, contact ChanMee Johnson via email at chanmee.c.johnson.civ@us.navy.mil. DISCLAIMER THIS NOTICE IS NOT A REQUEST FOR COMPETITIVE PROPOSALS. Responsible, interested parties, however, may identify their interest by submitting a capabilities statement. The Government will consider all information received prior to the closing date of this notice. A determination by the Government not to compete this procurement based upon responses to this notice is solely within the discretion of the Government.
