Archer Aviation vs. Firefly Aerospace: Which Aerospace Stock Is a Better Buy in 2026?

The article compares two aerospace companies: Archer Aviation, which develops electric vertical takeoff and landing (eVTOL) aircraft for urban air mobility, and Firefly Aerospace, which provides space launch services and lunar landers. Firefly is recommended as the better investment due to its lower valuation multiple (12.9x P/S vs. 626x), proven track record with a successful lunar landing, $1.4B in secured contracts, and 163% revenue growth. Archer faces higher risks from FAA certification delays and unproven commercialization, despite strategic partnerships with United Airlines.
