Top Defense Startups in 2026

Rocket engines make up 80% of the time and cost that go into a new vehicle. The modern rocket engine has thousands of components, utilizes a dangerous combination of chemicals, cost hundreds of millions of dollars to develop, take years to design, and still regularly fail. Firehawk Aerospace has created a rocket engine that can be custom designed in 4 to 6 months, is 1/5th the price of a competitor engine, is nearly environmentally benign, and has a ZERO TNT Equivalency (it will not explode). We are uniquely positioned to become a leader in the commercial industry due to our safety and low cost as well as the defense industry because our rocket engine can throttle down to 10%, turn off, and restart mid-flght. This is an incredible breakthrough for solid rocket fuel. To date Firehawk Aerospace's technology has been issued 5 U.S. patents, conducted 31 hot fire engine tests, and has signed a SPACE ACT AGREEMENT with NASA to occupy a testing facility to conduct more tests.

The product uses a mobile device with a near field reader (e.g., Android phone or tablet) to allow doctors and nurses to capture clinical quality data at the point of care quickly and efficiently. The data is then sent to a clinical decision support platform in the Amazon Cloud which analyzes the data in real time and provides advice and/or alerts to the clinical care staff at the bedside. And, the CDS platform allows for reporting and analysis of the data which can then be added to the electronic healthcare record, be analyzed for population health, used for quality improvement metrics, etc. This platform saves the clinical care staff valuable time that they would normally spend hand entering and analyzing the quality data onto paper based forms. The near field reader ability also saves them valuable time in having to hand enter patient ID data or bar-code scanning. The near field reader allows a provider to merely swipe their ID, the patient's ID, etc. with their phone or tablet.
