Meta CEO Mark Zuckerberg and Anduril founder Palmer Luckey — once on warring sides of the tech culture clash — are giving new meaning to the adage: all is fair in love and war.

The two executives buried the hatchet and announced a partnership Thursday to build next-gen extended reality gear for the US military. The system, dubbed Eagle Eye, will use AI and sensors in new headsets and other wearables to enhance vision, letting troops spot far-away threats with augmented reality, Luckey said on a podcast.

Anduril’s Lattice, its AI command-and-control platform, will provide real-time battlefield intel. The partnership will also use tech from Meta’s Reality Labs and Llama AI models.

The companies said they’re building the tech with “private capital, without taxpayer support,” promising to save the US military “billions of dollars,” Anduril said in a statement. They will also be using tech “originally built for commercial use.” Anduril raised $1.5 billion in August 2024 and is reportedly raising as much as $2.5 billion more, Reuters reported in February.
