This astonishing creation is a fully working replica of the U.S Glomar Explorer, constructed by Master MOCer and world-renowned builder Paweł ‘Sariel’ Kmieć, and you’re in for a truly remarkable story…

It’s 1968, and the Soviet ballistic missile submarine K-129 has been lost with all 98 crew, plummeting over 16,000ft to the ocean floor. It’s just a few years after the Cuban Missile Crisis and the Cold War is very real indeed. The Soviet Union is looking for its lost submarine, but 150 miles in the wrong place. The U.S. however, knows where it is…

And so begins one the strangest and most expensive recovery efforts in history, as the CIA commission the building of a ship designed solely to pluck the wreck of K-129 from the seabed to learn its secrets, without the Soviet Union knowing.

Costing $1.4billion, it was one seriously expensive recovery truck, although of course its true purpose was hidden behind a ‘drilling for magenese’ cover story, fronted by millionaire aviator and film-maker Howard Hughes.

Six years later and the 50,000 ton 600ft long ship was ready. Named the Transocean Glomar Explorer, it was positioned above the wreck using radio beacons (GPS being some way off) and the CIA began the enormous recovery of the 330ft, 2,700 long ton (before it was filled with water) nuclear-armed submarine.

A giant claw dropped through a moon pool in the centre of the ship, gripping the wreck of K-129 and winching it to the surface. However during the 16,500ft ascent a mechanical failure occurred, and two thirds of the submarine broke loose and sunk back to the ocean floor, taking with it the sought-after nuclear missiles and code book. However, two nuclear-tipped torpedoes and cryptographic machines were recovered, along with the bodes of six crew members, which were not returned to the Soviet Union, but back to the sea.

The Glomar Explorer was purposeless after the mission was (partly) completed, and in 1976 it transferred to the U.S Navy for storage in a dry-dock. In 1978 however, the ship was leased to test prototype deep sea mining equipment, before being converted to a drilling ship in the 1990s. It was finally scrapped in 2015.

Recreating this incredible feat of engineering is Sariel, whose floating brick-built replica of the Glomar Explorer measures over 3 metres in length, uses 60kg of LEGO pieces, and can really (partly) recover a lost Soviet submarine, thanks to a fully working recreation of the monumental grapple crane fitted to the real ship.

We won’t write too much more here as there’s really only one way to appreciate this spectacular build – take a look at the video above (or click here to find it in the Eurobricks discussion), and watch how one of the most impressive Lego creations of all time was built, and how it can recover nearly all of a brick-built submarine from the bottom of a swimming pool…
