Exhibit 1

PUBLIC INTEREST STATEMENT

1. Introduction

By the instant request (“Application”), DRS Sustainment Systems, Inc. (“DRS”) respectfully
requests that the Commission grant Special Temporary Authority (“STA”) to permit DRS to operate
the facilities specified in the attached Application.

Operation of the requested facilities is anticipated at this time to be required only from
6/20/2013-12/20/2013. Accordingly, issuance of an STA is appropriate pursuant to Commission
rules and policies.

2. Purpose and Nature of the Operation

The purpose of this test is to support a US government military contract known as the Joint
Assault Bridge (JAB). The relevant contract information is as follows:

- Contract No. - W56HZV-12-C-0150.
- Agency – US Army Contracting Command
- POC - Vince DiSanto (586)282-3546.

This test requires DRS to test both analog and digital transmission between two vehicle-borne
radio systems operating in the 30 to 87.975 MHz range. The purpose of the JAB system is to meet the
gap crossing requirements of the Operating Forces by providing a rapidly employable, short gap,
assault crossing system for the armored/mechanized forces, capable of spanning natural and
manmade obstacles up to 60 feet. DRS has performed numerous tests of this type of radio system in
the past in this area in support of several other government contracts under the auspices of radio
frequency authorizations issued by the relevant military customers. Tests were performed at the same
power level and ERP with no issues cited. For this test, testing is expected to only last for several
hours on one or two days during this period. If need be, DRS can perform these tests at any time
during the day or night to accommodate other users of this frequency space.

Waiver of the Station ID rules set forth at Section 5.115 is respectfully requested.
