US Navy Teletype Equipment - 1950's & 1960's

Individual TTY Equipment

Also See Torn Tape Relay Equipment

NOTE - This page mainly shows High-Level signaling (60ma current loop) equipment - In the 1960's, the Navy converted to TEMPEST MIL-STD-188B Low-Level signaling (+/- 6v) and there were equivalents to most all the High-Level equipment.

Brief Info on Typical 1980's Equipment

AN/UGC-77 Teletypewriter. The AN/UGC-77 is a militarized U.S. Navy standard teletypewriter that can be portable or fixed. The unit has a standard communications keyboard, 72 characters per line, friction-feed, synchronous motor, and a 7.42-unit code. Message traffic and operator notes are transmitted and received serially by means of a five-level binary permutation code. The AN/UGC-77 operates at 100 words per minute, weighs 59 pounds, and is 10 inches high, 16.5 inches wide, and 16 inches deep. Line voltage requirements are 115 V ac, single phase, 60 Hz.
AN/UGC-136 Teletypewriter. The AN/UGC-136 teletypewriter is a militarized, low-level, automatic send and receive teleprinter. It has storage, editing, and self-test capabilities. The AN/UGC-136 is controlled by a microprocessor with an internal solid-state memory and has full message composition and editing capabilities. It prints data nominally at 120 characters per second (1200 bps), can transmit or receive at data rates of 50 to 2400 bps, and can operate in switch-selectable Baudot or ASCII codes. The message storage module has a capacity of 12,288 characters. The AN/UGC-136CX is installed onboard submarines and the AN/UGC-136BX is installed on surface platforms. The primary difference between the AN/UGC-136CX and the AN/UGC-136BX is the AN/UGC-136BX has an LED display incorporated on the front panel to allow viewing of text for editing purposes when typed. The keyboard printer weighs approximately 59 pounds, is 8.5 inches high, 15.75 inches wide, and 17.4 inches deep. The power requirements are 115 V ac, 60 Hz, and 100 watts.
AN/UGC-143(V) Teletypewriter. The AN/UGC-143(V) U.S. Navy Standard Teletypewriter is a fully militarized unit. It features a modular design providing the compatibility for several different configurations: receive only with or without bulk storage; send/receive without bulk storage using the keyboard; or send/receive automatically with bulk storage. It prints 150 characters per second, ten characters per inch, six lines per inch and is capable of storing 500 kilobytes (250 messages, 2 kilobytes each). The power requirements are 115 V ac, 47-63 Hz, 440 watts, single phase. It weighs 180 pounds.
TT-624(V)5/UG or TT-624(V)6/UG Teleprinter. This teleprinter is used at CUDIXS, NAVMACS and TACINTEL installations. It may be used on-line with the AN/UYK-20 processor or off-line with tape readers, card equipment, and communications terminals. The device has a 64-character set capable of printing at speeds ranging from 365 lines per minute for 80 columns, to 1,100 lines per minute for 20 columns. It can print up to three additional copies using roll paper and five additional copies using fan-fold paper. The TT-624(V)5/UG is an ITA-2 Baudot printer with a serial MILSTD-188C interface; the TT-624(V)6/UG is an ASCII printer with an U.S. Navy Tactical Data System slow parallel interface. It weighs 270 pounds and requires 115 V ac, 60 Hz, single phase power.
TT-835/U System Console. The TT-835/U is a microprocessor-based teletypewriter communications terminal. It is used for system initialization, backup and recovery operations, and provides a record of SSIXS II shore system response and alerts. The keyboard provides man/machine interface for operator control of the SSIXS II shore operational program. The operator can enter parameters when conducting diagnostic or programmed maintenance testing.
RO-600/U Line Printer. The RO-600/U is a microprocessor-based receive-only printer. It is connected to the on-line AN/FYK-29 and is used to print incoming or outgoing messages and system reports. This device is employed in SSIXS II installations.
