A concept model was displayed in 2015 as a TC-1 modified with an imaging infrared seeker, folding control surfaces, free-rolling tailfins, a more-powerful rocket motor, and a trainable launcher with either eight or sixteen all up rounds and a FLIR sensor on its left-hand side.[1]
The design was finalized in 2017, which saw the missile's aft section enlarged in diameter to accommodate more rocket fuel and its four rolling tailfins replaced with eight smaller, fixed ones. The launchers have also evolved into two more-distinct variants: one that is integrated into the ship's central combat management system (as well as being completely reliant on it for targeting information) and has a capacity of 24 missiles but no onboard sensors, and an "autonomous" version that houses only twelve missiles but has its own rotating search/tracking radar and FLIR/Electro-Optical sensor, along the same concept as the SeaRAM system.[5]
In 2021 a Sea Oryx system was tested aboard the test ship ROCS Kao Hsiung.[4]
