- Back to the Drawing Board

- <p> Tipped with twelve nuclear warheads and carrying a price
- tag of $26.5 million each, the Trident II submarine-launched
- missile is supposed to give the U.S. the ability to destroy
- Soviet ICBMs still nestled in their silos. But hopes for the
- Trident's scheduled deployment in 1990 were set back last week
- when the weapon exploded during a test firing on the open sea.
- It was the second failure in three attempts; embarrassed Navy
- officials admitted that the probable reason for the misfires was
- a design flaw that should have been corrected on the drawing
- board.
- </p>
- <p> Because the new Trident is about 10 ft. longer and almost
- twice as heavy as the model it replaces, the missile leaves a
- more turbulent, gaseous wake as it rises to the ocean surface.
- But engineers miscalculated the amount of water that would rush
- into the vacuum under the missile's rocket nozzles.
- Investigators say these "water jets" interfere with Trident's
- trajectory and have led to the two mishaps. Their conclusion:
- the missile must be redesigned. Correcting Trident II could cost
- up to $20 million and delay its introduction for nearly a year.
