Boeing, Insitu & the Netherlands Organisation for Applied Scientific Research (TNO) have released updates on their Multi-function Radar Intelligence Surveillance Reconnaissance (MRaISR) project, an Industrial Participation initiative.

The MRaISR project, supported by the Dutch Ministries of Economic Affairs and Defense, focuses on creating a low Size, Weight, and Power (SWaP) Synthetic Aperture Radar (SAR) equipped with advanced collection and multi-mode capabilities designed to address emerging global defense requirements.

Two integrated payloads have been designed, built, and tested by TNO. They have successfully demonstrated airborne SAR image collection, Ground Moving Target Indicator (GMTI), and Inverse Synthetic Aperture Radar (ISAR) modes during three crewed flights over land and water in the Netherlands.

Philip Weimar, Director, Electromagnetics & Military Operations, TNO, commented, “At TNO, we are committed to advancing technology that supports national and international security but also reinforces our position as a leader in applied scientific research.

Brandy Pessin, Senior Manager, International Strategic Partnerships at Boeing, added, “The MRaISR project is a testament to our collaborative efforts between Boeing, Insitu, TNO, and Dutch industry and we are eager to showcase the results of our hard work. This collaboration strengthens defense capabilities, but also our key strategic partnerships within Europe, and is a great example of a win-win-win solution to building long term strategic partnerships.”

The project supports the Dutch Strategy for Industry and Innovation 2025–2029 (DSII) by developing TNO’s innovative AMBER radar technology into the MRaISR payload, which is intended to serve several of Boeing’s and Insitu’s customers. The collaboration also includes additional industry partners such as AcQ International, the Royal Netherlands Aerospace Centre (NRL), and Robin Radar.

Mark Lengton, deputy Commissioner for Military Production at the Ministry of Economic Affairs in the Netherlands, supported the project through the Dutch Industrial Participation policy. He noted, “This project allows TNO, as one of our leading knowledge institutes, and Dutch industry to partner with Boeing to develop a system that can be tested, demonstrated and industrialized.

In October 2025, a UAV flight demonstration of the MRaISR on an Insitu Integrator was completed at Insitu’s test range. Steven Todorov, Product Manager at Insitu, stated, “The MRaISR project exemplifies our mission to provide cutting-edge solutions that enhance situational awareness and operational effectiveness. Our partnership with Boeing and TNO has been instrumental in bringing this advanced radar capability to tactical UAVs, and we are excited to demonstrate its capabilities during the upcoming flight tests.”

A comprehensive business case analysis for the technology has been conducted, and an industrialization partner has been identified, with new product introduction planning already underway.
