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.

Catalogue of
NavShips 900,116-Supplement No. 5
1 October 1952




This supplement contains new and/or revised pages for the "Catalogue of Naval Electronic Equipment"-NavShips 900,116. These pages should be inserted in this catalog as follows:

1. Insert the new supplement title page in place of the former supplement title page.

2. The list of effective pages will not be revised since these supplements are to be printed more frequently pending delivery of a new overall catalog of electronic equipment presently under preparation.

3. Insert alphabetically new equipments or replace pages containing revised descriptions.



All of the equipments described in this second supplement are preliminary. They are compiled and issued in advance of equipment delivery for information only. Weights and dimensions are approximate, and are not, repeat, NOT to be used for installation planning.

Washington, D. C., 15 April, 1946

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.

Vice Admiral, USN,
Chief of the Bureau of Ships.

1 NavShips 900,116 is an interim publication pending official cataloguing of Bureau of Ships electronic material.



In this Catalogue equipments are designated by four nomenclature systems: (1) Navy Model Letters, (2) Army-Navy Nomenclature, (3) Signal Corps, and (4) Navy Type Numbers.

The charts which appear on the following pages are included for convenient reference in

  cases where the reader may desire to identify some unit or equipment from its nomenclature. No attempt is made to explain these systems in detail or to supply all the rules which go into the assignment of such nomenclature.

Army-Navy Nomenclature System

The Army-Navy Nomenclature system (AN System) is applied by the Army to all its equipments and by the Navy to its air-borne equipment or to other types which are procured jointly by the two services. The system applies not only to complete equipments but to component units. The letters "AN" indicate that a complete equipment is described (as AN/ TPS-1), while components of the equipments are described by an indicator followed by the model letters of the complete equipment with which the unit was first used (T-2/ARC-6).

Navy Model Letter System

Navy Model Letters are assigned to complete equipments. In general, two-letter combinations are assigned first, and when the alphabet is exhausted three letters are used. (RAA is a later assignment than RU; RBA is later than RAA.) In some equipments the second letter   designates a subclassification indicated in the second column of the table. (QCS is in a different category from QBF and not necessarily a later assignment. However, QCU is later than QCS.)
