This legislative proposal, known as the PRIME Act, amends Section 4023 of title 10, United States Code, to significantly modify procurement for experimental purposes. It broadens the definition of items eligible for such procurement to include a wider range of defense-related articles , such as demonstrations, prototypes, products, and auxiliary services, moving beyond previously specified categories. The bill also introduces greater flexibility in experimental purchases, explicitly allowing for modifications and including prototyping as a valid reason for procurement. A key provision enables follow-on production contracts or transactions for successful experimental items without requiring competitive procedures or additional justification. This streamlined process is contingent on a combatant command's written determination that the item was successful and will be fielded, aiming to accelerate the deployment of new military equipment.
