MAST IDIQ - Low Probability of Intercept Altimeter (LPIA) Production and Repair
The Office of the Secretary issued solicitation N00421-26-RFPREQ-TPM209-0264 as a Sources Sought notice to identify qualified parties for the Low Probability of Intercept Altimeter (LPIA) program. This market research effort supports an anticipated Indefinite Delivery Indefinite Quantity contract for the production, engineering, logistics support, delivery, and repair of LPIA units, specifically the R/T-1805/APN Receiver/Transmitter and associated software. This requirement is classified under NAICS 334511 Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing and PSC 5841 RADAR EQUIPMENT, AIRBORNE. The notice specifies an 8AN 8AN set-aside.
The LPIA is a radar altimeter utilized by multiple military services that employs frequency-hopped, spread-spectrum waveforms to reduce the probability of signal interception and jamming. Operating within the 4200 MHz to 4400 MHz band, the LPIA R/T-1805/APN serves as a form, fit, and enhanced function replacement for the AN/APN-194(V) family of receiver transmitters. The scope of work includes managing component obsolescence, military aviation software development, and lifecycle logistics. Primary performance is located in Wayne, NJ, following the incumbent contract held by BAE Systems, which concludes in May 2026.
Interested parties are requested to submit a capability statement of no more than 10 pages by the May 26, 2026, deadline. Submissions must detail the company’s ability to perform the scope of work, relevant past performance, and facilities. Documentation should be sent to Contract Specialist Grace Gillespie. The government will use the gathered information to determine the feasibility of the requirement and to identify potential sources capable of meeting the LPIA specification and interface requirements.

This is a Sources Sought notice for market research purposes only. This is not a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information from qualified and interested parties regarding their capabilities to provide comprehensive support for the Low Probability of Intercept Altimeter (LPIA) program. The Government will not reimburse respondents...
View moreThe LPIA is a radar altimeter used across multiple military services that utilizes a frequency-hopped, spread-spectrum waveform to reduce its probability of being detected. This advanced processing allows for high accuracy and resistance to jamming.
2.0 Scope of Work
The Government is seeking sources capable of performing the following efforts to support the LPIA system and its associated software. The LPIA R/T-1805/APN Receiver/Transmitter (R/T) is an advanced technology radar altimeter required by Naval Air Systems Command (NAVAIR) to improve survivability, reliability, and maintainability of fleet aircraft. The LPIA operates in the radar altimeter band of 4200 MHz to 4400 MHz. The LPIA accurately determines the aircraft’s height above the terrain and incorporates techniques to achieve a very low probability of signal interception, detection, or exploitation. The LPIA R/T is a Form, Fit and enhanced Function (FFF) replacement for the AN/APN-194(V) family of receiver transmitters, RT-1015A/A and RT-1042A/A. The LPIA must conform to the current LPIA specification, waveforms, Radio Frequency characteristics and responses, interfaces and work with antennas currently installed on aircraft that have the LPIA installed. The contractor shall provide production, engineering and logistics support, delivery and repair of LPIA units.
3.0 Required Capabilities and Experience
Interested parties should demonstrate experience, knowledge, and capabilities in the following areas:
Proven experience with radar altimeters, particularly those with Low Probability of Intercept (LPI) characteristics.
Demonstrated capability in managing obsolescence, including component redesign and re-qualification.
Experience in providing lifecycle logistics, engineering, and technical support for complex avionics systems.
A robust supply chain management system for procuring authentic and reliable electronic components.
Experience with military aviation software, including development, testing, and licensing.
4.0 Submission Requirements
Interested businesses are requested to submit a capabilities statement. The statement shall be limited to a maximum of 10 pages and should include the following information:
