PROMONTORY, UT—Northrop Grumman Corp. is using innovative modular tooling to manufacture large composite cases for solid rocket motors.

Northrop’s modular mandrel tooling can change in shape and size, allowing the defense contractor to make rocket motor cases of varying length and diameter. The capability of the hardware to support multiple designs with varying dimensions allows engineers to quickly implement new case designs or modify existing ones to accommodate changes during design and production.
