TL;DR / Executive Summary
- Seraphim portfolio company Array Labs has raised an additional $21 million in an oversubscribed funding round, led by Mitsubishi Electric.
- The funding will support the development of Array Labs’ radar satellite constellation, designed to provide continuous monitoring of aircraft, ships and other activity from orbit.
- Array Labs has already secured research and development contracts with DARPA, the US Navy and the US Air Force.
- The raise highlights growing investor interest in next-generation space-based intelligence and surveillance technologies.
Array Labs has raised $21 million in an oversubscribed strategic investment round, anchored by Mitsubishi Electric Corporation, one of Japan’s largest defense and aerospace companies, with continued participation from Catapult Ventures, Kompas VC, and Y Combinator. As part of the financing, Array Labs and Mitsubishi Electric have entered into a partnership to develop and bring to market satellite-based airborne tracking services for mainly defense and security customers in the Asia Pacific Region.
“Defense and intelligence customers have been asking for this capability for years, and this round lets us move faster to deliver it. An oversubscribed round anchored by a partner of Mitsubishi Electric’s caliber is a strong signal that the market sees the same opportunity we do,” said Isaac Robledo, COO and cofounder of Array Labs.
This investment follows Array’s Series A fundraise, announced in January 2026.
Unlocking Continuous Understanding of Earth
Traditional satellites are designed to image the ground. They periodically capture static, two-dimensional scenes: terrain, objects, infrastructure. They aren’t built to capture the motion, change, and activity happening around the world in real-time.
Real-time monitoring of aircraft and ships has long been recognized as a critical capability gap. While a static image might tell you about a location at some point in the past, a continuous feed provides insight into how things are changing, where, and how fast.
Traditional satellites cannot detect movement. Ground-based radar systems are constrained by the horizon line. Airborne ISR platforms have greater range, but are limited by cost, survivability, and operational constraints. Governments managing complex airspace, monitoring contested borders, and tracking activity across wide areas require a persistent orbital solution capable of continuously monitoring airborne and maritime activity anywhere on Earth.
Array Labs is the difference between reacting to yesterday’s picture of the world and understanding today’s dynamic environment in real time. That shift changes what’s operationally possible: persistent awareness instead of periodic captures, patterns of life instead of isolated data points, and high-fidelity visualizations that show activity unfolding, rather than reconstructing it after the fact.
The New Playbook
Array Labs takes a fundamentally different approach to building radar satellites. Instead of relying on a single large, expensive satellite, Array builds mass-manufacturable radar satellites that fly in a cluster, operating together as one distributed sensor in orbit. By combining advanced signal processing algorithms, formation-flying satellites, and manufacturing techniques from modern telecommunications, semiconductors, and consumer electronics, Array can deliver higher power, wider coverage, and higher resolution systems at a cost and scale traditional space systems were never designed to achieve.
The result is a continuously updated picture of the Earth that captures not just terrain and infrastructure but everything moving across or above it, including 3D and 2D imaging, naval and airborne monitoring, and space-situational awareness. No other commercial satellite operator offers this breadth of capability within a single integrated platform.
Array has validated its core formation flying and multistatic technology, and earned competitive research and development contracts with DARPA, the U.S. Navy, and the U.S. Air Force.
Array Labs and Mitsubishi Electric Partnership
Mitsubishi Electric is one of Japan’s largest defense and aerospace contractors, supplying advanced electronics, radar, and satellite systems to the Japanese Ministry of Defense for over half a century. In February 2026, it was awarded a contract to develop and manufacture Japan’s next-generation defense satellite system.
This partnership brings together Array’s transformative approach with Mitsubishi Electric’s satellite system development capabilities, manufacturing infrastructure, and established relationships with defense, government, and other customers across the Asia-Pacific region. Together, Array and Mitsubishi Electric will bring moving object detection and tracking services to defense, security, and related customers.
“We are very pleased to collaborate with Array Labs, which aims to demonstrate its game-changing AMTI technology. By combining the technological capabilities and maximizing the synergies of our two companies, we expect to strengthen our ability to respond comprehensively to customer needs in the security field,” said Masahiko Arai, Executive Office, Company President, Defense and Space Systems, Mitsubishi Electric Corporation.
“Mitsubishi Electric Corporation’s deep mission insights and defense relationships across Asia-Pacific make them an ideal partner. We’re excited to work together to turn space-based AMTI into an operational reality, helping humanity better understand the physical world,” said Andrew Peterson, CEO and cofounder of Array Labs.
