Ursa Major Technologies is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ursa Major Technologies rather than just read about it. In short: Ursa Major Technologies is an American aerospace company founded in 2015 and based in Berthoud, Colorado. The company produces rocket engines for customers in the space launch and hypersonics industries, and the US Federal Government.

Key takeaways

Ursa Major Technologies belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ursa Major Technologies to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ursa Major Technologies from memory before moving on to harder problems.

Reference excerpt

Ursa Major Technologies is an American aerospace company founded in 2015 and based in Berthoud, Colorado. The company produces rocket engines for customers in the space launch and hypersonics industries, and the US Federal Government. The company makes a 5,000-pound thrust liquid oxygen and kerosene Hadley engine, named after a character in Ray Bradbury's The Veldt. It also develops the Ripley engine, with 50,000 pounds (23,000 kg) of thrust, aimed at the medium-launch market. Its commercial customers include C6 Launch Systems, a Canadian small satellite launcher, and American launch startup Phantom Space. It also works with Generation Orbit Launch Services and with Stratolaunch, supplying Hadley as the rocket engine for the latter.

History In 2017, Ursa Major raised US$8 million with participation from the Space Angels Network. In December 2021 the company closed its largest funding round to date: an US$85 million Series C led by funds and accounts managed by BlackRock. In April 2023 the company had about 270 employees. The company announced that it would supply the upper stage engine for Astra Space’s in-development Rocket 4. As of 2024 its Draper prototype engine demonstrated stability similar to solid fuels, along with the active throttle control and throttle range of a liquid engine.In February 2026 it presented the HAVOC Missile System, a hypersonic weapon powered by Draper. According to Nick Doucette, co-founder and vice president at Ursa Major, in an interview with The War Zone, “China has had boost-glide hypersonics for a decade. Other hypersonic designs use a scramjet, which are costly and complex. Draper opened up hypersonic performance, where you have a wide range of trajectories and adaptability as well as other really creative mechanisms that, to be honest, the adversaries don’t have." It is said that the system can effectively bridges the gap between hypersonic flight and ballistic missiles by supplying users with the capability of switching capabilities at a moment's notice.

Worked examples

Example 1 — a first encounter with Ursa Major Technologies

Start with the simplest possible case. Write down what Ursa Major Technologies claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ursa Major Technologies before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ursa Major Technologies ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ursa Major Technologies

In research: Ursa Major Technologies appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ursa Major Technologies in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ursa Major Technologies is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerospace companies of the United States, American companies established in 2015, Private spaceflight companies, so understanding it makes those chapters shorter.
In everyday life: Look for Ursa Major Technologies outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
