Company profile
researched Aug 2026Rain develops a wildfire mission autonomy system that adapts military and civil autonomous aircraft to perceive, understand and suppress wildfires. The system interprets a fire's behavior, size and direction of spread and uses that information to design a suppression strategy, accounting for subsequent responding aircraft, their resources and arrival times in order to build a coordinated aerial suppression plan; ground crews complete final suppression. Rain also uses simulation that combines fire propagation and fire suppression modeling to determine how many aircraft are needed to contain or slow an ignition before it reaches an inflection point.
The company positions its technology as an additional layer of safety for human-piloted missions and as a means of commanding networks of uncrewed aircraft prepositioned in remote areas to shorten response times. Its concept of operations builds on existing early-detection infrastructure, including more than 1,100 early fire watch cameras in California and additional cameras across the American West. Rain states that its team has worked alongside fire professionals since inception and has direct experience with catastrophic wildfire.
Traction
Rain and Sikorsky demonstrated an autonomous Black Hawk helicopter being commanded to take off, locate and size a small fire and drop water on it, and subsequently conducted a two-week demonstration of autonomous wildfire suppression in a representative wildfire environment in California, which included the first demonstrated communication interoperability between an autonomous aircraft and a human-piloted helicopter in the same Fire Traffic Area under supervision of an Orange County Fire Authority air tactical group supervisor aircraft. Rain's perception system is also being integrated with a Black Hawk operated by Brothers Air Support, its first integration with a private firefighting aircraft.

Market position
Rain's approach has been publicly endorsed by senior fire service figures, including Chief Brian Fennessy of the Orange County Fire Authority and FIRESCOPE chair, former California State Fire Marshal Kate Dargan Marquis, former CAL FIRE Chief Deputy Director Christopher Anthony, and Chief Dan Munsey, chairperson of the International Association of Fire Chiefs Technology Council.
Technology
Rain's wildfire mission autonomy system provides perception and mission planning for autonomous aircraft: it detects and characterizes a fire, determines its size, behavior and direction of spread, and generates a suppression strategy that incorporates additional responding aircraft and their arrival times. The system uploads mission commands to autonomous rotorcraft, and has been operated in conjunction with Sikorsky's MATRIX autonomy suite on an Optionally Piloted BLACK HAWK helicopter. A separate wildfire perception system is being integrated onto a privately operated Black Hawk firefighting helicopter. Rain also employs coupled fire propagation and suppression simulation to size the aircraft response required for a given ignition.
Go-to-market
Rain works through collaborations with aircraft and autonomy providers and firefighting operators, integrating its autonomy and perception software onto existing helicopter platforms. Announced efforts include a collaboration with Sikorsky, a Lockheed Martin company, unveiled at UP.Summit, live-fire and test-fire demonstrations attended by government, firefighting agency and investor representatives, and a partnership with private Black Hawk operator Brothers Air Support.
Fire agencies and aerial firefighting operators, including public fire and emergency response agencies and private firefighting aircraft operators such as Black Hawk helicopter operators.
Geography
Activities described are in California and the American West, where early fire detection camera networks are deployed and where live-fire demonstrations were conducted.

launches, deals, and filingsRain and Sikorsky demonstrated how an autonomous Black Hawk helicopter can be commanded to take off, identify the location and size of a small fire, and drop water to suppress the flames, observed by government, firefighting agency and investment representatives.
Rain announced a partnership with Brothers Air Support, a private Black Hawk firefighting operator, to equip its helicopter with Rain's wildfire perception system β the first integration of Rain's system with a private firefighting aircraft.
Announced at UP.Summit, the collaboration explores how Sikorsky's MATRIX autonomy suite operating with Rain's Wildfire Mission Autonomy System can launch uncrewed helicopters to drop water on wildfires within minutes of detection, using Rain's system to upload mission commands to Sikorsky's Optionally Piloted BLACK HAWK helicopter with no crew on board.
Rain and Sikorsky, a Lockheed Martin company, demonstrated autonomous wildfire suppression technology in a representative wildfire environment in California over two weeks, including the first demonstrated communication interoperability of an autonomous aircraft with a human-piloted helicopter in the same Fire Traffic Area, supervised by an Orange County Fire Authority air tactical group supervisor aircraft (HLCO).
