TB-29/BQ
Towed Array
The TB-29 series array
represents the cutting edge in submarine
thin line towed arrays. It is intended
for use with the AN/BQQ-5(E) sonar
system and the AN/BSY-1 and BSY-2
submarine combat systems. Its increased
length over earlier arrays allows the
TB-29 series array to provide superior
detection, classification, and localization
performance.
The technology for the
TB-29 series array is mature: full-scale
engineering development testing is
complete and limited rate initial
production is underway.
Production and reliability of
the TB-29 series array benefit greatly from the new, state-ofthe-art
towed array facility that Lockheed Martin has established
in Syracuse, New York.
This world-class facility offers:

• The only industrial, Navy-certified, heading sensor calibration
facility in the world along with a Navy-certified acoustic
calibration facility.
• A fully automated module “hose and fill” facility that
simultaneously installs electronics and fills array modules
with oil.
The TB-29 series
array provides
the fleet with longrange
detection,
enhanced target
classification ability,
and improved
localization, while
allowing our
submarines to
operate with
increased tactical
speed.
• A non-invasive X-ray inspection of all array electronics
placements.
• A battery of automated test equipment and recording
procedures.
The TB-29 series array, produced at Lockheed Martin
Ocean Systems Center of Excellence, is ready today to provide
our submariners with the tactical advantages they need to
meet the threats of the next century.

TB-16/BQ
Towed Array
Lockheed Martin participated
in the development of the
TB-16 series of “towed bodies”
in the early 1970s and began
production of TB-16 towed
arrays in 1975. Since then,
more than 300 arrays have
been delivered to the
U.S. Navy.

Starboard elongated “bump” contains the
TB-16/BQ towed array.
TB-16 arrays have been installed on SSN 637,
SSN 688, Seawolf and Trident class submarines. The TB-16
is known as a “fat-line” array due to its more than three-inch
diameter. When stowed, it is housed in a tube that runs fore
and aft along the ship’s hull. The tube is visible as an elongated
“bump” when the submarine is on the surface.
Throughout the long service life of the TB-16,
Lockheed Martin has initiated several improvement programs
for the array. One such program was the TB-16B, which greatly
reduced the self-noise of the array. This version has been in
production since 1987. A digital version of the array, the
TB-16D, has also been delivered to the fleet. It is designed
to be compatible with the AN/BQQ-5D sonar system and
the AN/BSY-1 and AN/BSY-2 combat control systems. In
December 1989, Lockheed Martin was awarded a contract
for the production of 69 TB-16E systems. In March 2003,
Lockheed Martin was awarded a contract for the production
of TB-16G systems.

Center of Excellence
Lockheed Martin’s towed array
production and refurbishment
activities will be completed in
a new, dedicated, 220,000 square
foot, world-class facility, which
includes a complete life-cycle
support depot.
• Towed array programs are based in Syracuse, NY,
and have been designated an Ocean Systems Center
of Excellence for Navy programs.
• Provides single source customer service — from design
concept through fleet support.
• Investment in new 220,000 square foot world-class
facility for towed array programs demonstrates corporate
commitment.
