We build defence products with wartime urgency.

Bifrost Defence is a multi-product defence company. We source capability gaps from the war fighters who live them, build the product on one shared core of military relationships, go-to-market, procurement and finance, and field it while the need is still current.

We build defence products, together with the people that field them.

Whether you are an investor, a prime, a ministry or an engineer with a problem you have lived, we want to hear from you. Bring the capability gap; we bring the platform that closes it.
