The procurement is set aside for small businesses and involves the repair or modification of electrical converters, which are critical components in various military applications. Interested parties are encouraged to submit their capabilities and proposals within 45 days of the notice, with the understanding that the government intends to negotiate with only one source due to the proprietary nature of the required data.
