What is the approved budget of Dragonfly Titan mission?

Dragonfly is NASA's New Frontiers mission to send a nuclear-powered octocopter rotorcraft lander to Saturn's moon Titan, led by the Johns Hopkins Applied Physics Laboratory, with launch readiness in July 2028 on a Falcon Heavy and arrival at Titan in 2034. The NASA Office of Inspector General reported in September 2025 that when NASA established the project baseline in April 2024 its life-cycle cost had grown to 3.35 billion dollars, more than double the 850 million dollar cost cap of the original selection.
