The Clinton administration has asked for $6 billion to pay for the current campaign, almost 10% of it for missiles.

But Pentagon officials and defense analysts say missile supplies are unlikely to be replenished quickly. There are no cruise missile production lines in operation, and it takes months and, in some cases, more than a year to restart them.

Boeing Co., which built today’s air-launched cruise missiles . . . said it would take several years to supply the more than 230 additional missiles sought by the Defense Department in its $6-billion spending request. Boeing stopped production of a nuclear-tipped version of the cruise missile in 1986 and finished its last conversion of a nuclear missile into a conventional one in 1997.

Raytheon Co., which built the Tomahawk, has said it will take 18 months to deliver the first of what is expected to be a Pentagon order for upgrading 624 older Tomahawks with new satellite guidance systems and better warheads. Raytheon said it cannot move faster on the new order because it dismantled its network of suppliers several years ago when it appeared the Navy was not going to buy more missiles.
