Catalogue of Electronic Equipment,-NavShips 900,116, 1952, is a Navy catalog of electronics that includes almost all the WW II equipment and some of the earliest Cold War equipment.

The Navy stopped issuing fresh list of Effective Pages with the 2nd update. For this online version of the 5th update we have replaced the incomplete Navy supplied list of Effective Pages with a Table of Contents that matches the pages as found in the print copy. This Table of Contents is easily searched within a browser.

HNSA thanks USS Pampanito for the generous loan of the original document used to create this online version.

Please report any problems with the HNSA Feedback Form for correction.

Foreword

1. "Catalogue of Electronic Equipment," NavShips 900,116, is a CONFIDENTIAL nonregistered publication and shall be handled in accordance with U. S. Navy Regulations. Periodic accounting is not required. While the Catalogue as a whole is considered to be confidential, it will be noted that each page carries a classification in accordance with the security applicable to the equipment involved.

2. NavShips 900,116 replaces the earlier edition of the Catalogue known as SHIPS 275, and upon receipt hereof all copies of SHIPS 275 should be destroyed. It does not replace the "Catalogue of Electronic Test Equipment," NavShips 900,105. However, the two publications may be brought together under a single cover if such combination serves the user's purpose to better advantage.¹

3. The purpose of this publication is to supply a convenient and summarized reference of the principal Bureau of Ships electronic equipments (except air-borne). It is obviously beyond the scope of this publication to list all the data on any equipment. Where more complete information is desired it will always be necessary to consult the instruction book. To identify equipments not appearing here, the reader is referred to the "List of Naval Electronic Equipment" (SHIPS 242A).

4. This publication had been made loose-leaf so that correcting pages or descriptions of new equipments can be added from time to time. Pages are arranged alphabetically according to the model letter of the equipment, or, in the case of type-numbered components, numerically. When new equipments are added, insert the pages in their proper alphabetical place. At the back of the Catalogue is a section entitled "Miscellaneous" in which will be found those equipments which do not carry any standard Army or Navy nomenclature.

5. This publication contains information affecting the national defense of the United States within the meaning of the Espionage Act (U. S. C. 50; 31, 32) as amended.

6. Additional copies may be secured from the Bureau of Ships.
