Three months after coming into Elliott Bay, the Missile Defense Agency’s Sea-Based X-band Radar (SBX) vessel headed out of town.

Armand sent us these photos of the odd-looking platform that has been docked at Vigor Shipyard Seattle for maintenance and upgrades.

The photos were taken from Sunset Hill Park around 4:30 on Saturday afternoon. You can track the journey of the SBX here – just search for SBX 1.
