Archer Aviation shares jumped 18% in session trading after the company unveiled a new military-grade aircraft developed in partnership with defense technology firm Anduril Industries.

The announcement marks a significant expansion of Archer’s addressable market, moving beyond its primary focus on urban air mobility to include defense applications.

The price surge reflects investor enthusiasm for the diversification of Archer’s revenue streams.

While the company remains heavily reliant on the successful certification and launch of its commercial eVTOL vehicles, the defense contract offers a potentially more immediate and less regulatory-heavy path to revenue.

The partnership with Anduril, a leader in autonomous systems and defense tech, lends credibility to Archer’s engineering capabilities in high-stakes environments.

Archer Aviation CEO Adam Goldstein emphasized that the company remains "laser-focused" on achieving FAA certification for its commercial air taxis in time for the 2028 Los Angeles Olympics.
