MV Sycamore is a training ship built to support the Royal Australian Navy (RAN) by Netherlands shipbuilders Damen Group.

[2] The RAN classes Sycamore as a "multi-role aircraft training vessel", and the ship is equipped with a hangar and a flight deck, allowing a single helicopter to land.

Sycamore is the first ship to support the Australian Defence Force (ADF) designed from the outset to be able to operate unmanned aerial vehicles (UAVs).

Sycamore is the RAN's first dedicated training ship since HMAS Jervis Bay was decommissioned in 1994.

[9] In 2021 the RAN entered into negotiations with Damen to purchase a ship based on Sycamore's design that could be used for humanitarian assistance in the Pacific.

These negotiations ended in failure, and the RAN acquired a secondhand offshore supply vessel instead which entered service in 2022 as the ADV Reliant.
