MAST IDIQ - Low Probability of Intercept Altimeter (LPIA) Production and Repair

The 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: 

Company Information: 

• Company Name and Address 

• Unique Entity ID (UEI) and CAGE Code 

• Point of Contact (Name, Title, Phone, and Email) 

Business Size/Status: 

• Indicate your business size under the specified NAICS code 334511. 

• Specify any socioeconomic status, such as Small Business, 8(a), Woman-Owned Small Business (WOSB), Service-Disabled Veteran-Owned Small Business (SDVOSB), or HUBZone.  

Capabilities Statement: 

• A description of your company’s ability to perform the Scope of Work (Section 2.0). 

• A summary of relevant past performance on contracts of similar size and scope with government or commercial entities. Please include contract numbers, customer points of contact, and a brief description of the work performed. 

• A description of your company's facilities, personnel, and quality assurance processes. 

5.0 Submission Instructions 

Please submit your capability statement via email to Grace Gillespie at [email protected] no later than 4:00pm on 23 May, 2026. Please use the subject line: "Response to Sources Sought for LPIA IDIQ".
