GENERAL OF  HE        STATES


THE NAVY'S ADVANCED LIGHT-
WEIGHT TORPEDO: A NEW
WEAPON THAT FACES MANY
DEVELOPMENT CHALLENGES


DIGEST

The Advanced Lightweight Torpedo (ALWT) is
the Navy's newest antisubmarine warfare
weapon. It is intended as the replacement
for the Navy's current lightweight torpedo,
the MK-46.

In July 1979 the ALWT program received ap-
proval to begin advanced development, and in
August 1979 two competitive advanced devel-
opment contracts were signed. Both contrac-
tors are to competitively design, build, and
test their proposed ALWT concepts, leading
to a full-scale engineering development
decision in April 1983.

GAO noted the following during its review:

--ALWT is intended to address the advancing
  Soviet submarine threat and overcome defi-
  ciencies in current lightweight torpedoes.
  However, the severity of the Soviet threat
  has increased signficantly since the ALWT
  requirement was issued, particularly in
  the areas of speed and depth capability.
  Thus, the advanced development baseline
  design may require enhancement. The Assis-
  tant Secretary of Defense has recommended
  that the Navy begin efforts to develop en-
  hancements to key subsystems such as the
  warhead and propulsion. (See pp. 19 and
  20.)

--Navy analysis has shown there is no viable
  alternative to developing a new lightweight
  torpedo. Other free world torpedoes avail-
  able or under development do not possess
  the performance necessary to satisfy the
  Navy's requirements. (See pp. 3 and 6.)
