Ammunition and Weapon Systems Engineering Services

Providing environmental and engineering solutions from initial ideas through design/analysis, prototype testing/evaluation to production



Concurrent Technologies Corporation (CTC) uses a “design-to-production” approach, examining the entire process/system lifecycle, from environmental concerns to producibility. CTC’s full-service solutions team consists of engineers, scientific experts, technicians, and project managers with in-depth experience in materials, design, analysis, rapid prototyping, testing, and manufacturing.

Innovative, Full Lifecycle Engineering Solutions
Both the Department of Defense (DoD) and the commercial industry can benefit from CTC’s award-winning approach to ammunition. The National Armaments Consortium and the DoD Ordnance Technology Consortium recognized CTC for Outstanding Technical Achievement for its groundbreaking manufacturing process that improves logistics and the end product. CTC is developing and testing prototype ammunition cartridges that:
  • Increase performance
  • Improve accuracy
  • Reduce weight
  • Reduce manufacturing footprint
  • Lower the total cost of ownership
This work is building on decades of experience developing industry-leading engineering solutions that cover research and development through testing, technology transition, and implementation.

Ammunition

high-bay demonstration space
Developed a single-piece stainless steel cartridge case that can increase lethality, improve accuracy, and reduce cartridge weight
CTC has utilized advanced metal injection molding (MIM) processes to develop a single-piece, high-strength stainless steel cartridge case that is stronger, stiffer, and lighter than traditional brass. The metallic design allows for trade space between weight reduction and lethality with affordable costs in mass production.

Weapon Systems

high-bay demonstration space
Novel manufacturing approaches provide more than $40 million cost savings
CTC improved the affordability of the 155MM howitzer by converting multi-part components to single-piece titanium investment castings, including simplifying the 60-part saddle to one-part. The casting process and other innovative production processes reduced costs by $40 million for the initial-rate and full-rate production of nearly 590 guns, with proportional cost avoidance for subsequent orders.

Process Development and
Optimization

high-bay demonstration space
Development of a coating process for steel tipped enhanced performance round (EPR) penetrators to improve their corrosion resistance
CTC is improving the environment compatibility, shelf life, and ruggedness of Army EPR ammunition through development, test and evaluation of enhanced corrosion coatings for steel tipped projectiles. Corrosion testing, rough handling, and first article testing were performed prior to technology transition and production implementation.

Support

high-bay demonstration space
Production line successfully transitioned to client facility, allowing client to meet deliverable schedule
CTC developed the M-72 FFE production line to assist our client with meeting their deliverable schedule for qualification units. CTC built jigs/fixtures and quality test equipment in addition to setting up a production line for preproduction/debug and LRIP/qualification. The production line was transitioned to the client facility, and CTC provided setup and training to the client’s employees.
