About LEGO Deep-Sea Research Submarine
Built from 413 pieces, this submarine model measures 25 cm long, 15 cm high and 15 cm wide. The set is designed for builders aged 9 and up and features realistic mechanical elements that demonstrate how submarines operate.
The model includes rotating propellers and an extending grabbing arm that can pick up the included barrel accessory. The transparent cockpit opens to reveal detailed interior controls and seating. These functional features help demonstrate basic submarine mechanics and underwater operations.
Key Features
The submarine's grabbing arm extends and retracts to collect objects, while the propellers rotate to show propulsion mechanics. The opening cockpit provides access to detailed interior elements including pilot controls and seating arrangements.
This Technic set introduces basic engineering concepts through realistic movement and mechanical functions. The building experience focuses on understanding how submarine systems work rather than purely decorative construction.
