1.   As a result, neither side is willing to stop building missiles and tinkering with warhead designs as a hedge against surprises and as a deterrent against attack.

2.   But the conservatives would like to conduct a quick burst of up to five test blasts next year to help simulate future tests of warhead designs by computer.

3.   But they become more valuable when combined with specific performance data, which would then enable someone to generate a computer simulation of American warhead designs.

4.   It is partly because he thinks America might need to test unusual warhead designs such as this that Bush refuses to ratify a test ban.

5.   The congressional report does not name the specific warhead design suspected of being stolen by China.

6.   The report said China stole U.S. nuclear warhead designs, advanced radar know-how and missile-guidance-system-blueprints.

7.   These mobile missiles require small warhead designs, of which the stolen U.S. design information is the most advanced in the world.

8.   This is an essential tool in warhead design.
