Whoever, with intent to injure, interfere with, or obstruct the national defense of the United States, willfully makes, constructs, or attempts to make or construct in a defective manner, any national-defense material, national-defense premises or national-defense utilities, or any tool, implement, machine, utensil, or receptacle used or employed in making, producing, manufacturing, or repairing any such national-defense material, national-defense premises or national-defense utilities, shall be fined under this title or imprisoned not more than ten years, or both.
If two or more persons conspire to violate this section, and one or more of such persons do any act to effect the object of the conspiracy, each of the parties to such conspiracy shall be punished as provided in subsection (a) of this section.
(June 25, 1948, ch. 645, 62 Stat. 800; Sept. 3, 1954, ch. 1261, title I, § 105, 68 Stat. 1218; Pub. L. 103–322, title XXXIII, § 330016(1)(L), Sept. 13, 1994, 108 Stat. 2147; Pub. L. 104–294, title VI, § 601(f)(12), Oct. 11, 1996, 110 Stat. 3500.)
Historical and Revision Notes

Based on section 106 of title 50, U.S.C., 1940 ed., War and National Defense (Apr. 20, 1918, ch. 59, § 6, as added Nov. 30, 1940, ch. 926, 54 Stat. 1221).

Reference to persons causing or procuring was omitted as unnecessary in view of definition of “principal” in section 2 of this title.

Words “upon conviction thereof” were omitted as unnecessary, since punishment cannot be imposed until a conviction is secured.

Minor changes were made in phraseology.
