Lego Technic Deep-Sea Research Submarine

Plunge into the mysteries of the ocean with the LEGO Technic 42201 Deep-Sea Research Submarine. This 413-piece building set lets young builders aged 9 and up create a realistic, functional sub packed with authentic details.

The see-through bubble cockpit opens to seat a mini figure (not included), while rotating thrusters and posable grabber arms make it easy to imagine collecting samples from the seafloor. A removable research pod and a seabed build with treasure elements add extra storytelling possibilities.

As kids build, they explore core STEM concepts such as gearing, buoyancy and mechanical movement. When the mission is complete, the finished model makes a striking display piece for any bedroom or playroom.
