General characteristics
TypeBattlecruiser
Displacement27,988 tonnes (27,546 long tons; 30,851 short tons)[2]
Length
  • 236 m (774 ft) p.p.[2]
  • 241.2 m (791 ft) overall[2]
Beam
  • 29.4 m (96 ft) (outside armor)[2]
  • 30.85 m (101.2 ft) (upper deck)[2]

  • Underwater protection: Bulge below main side belt (depth 1.5 m (4.9 ft))[A 3]
  • Conning tower: 150 mm (5.9 in)[2]
  • Steering compartment: 150 mm (5.9 in)[2]
  • Steering compartment main deck: 125 mm (4.9 in)[2]
  • Armored bulkhead: 40 mm (1.6 in)[2]
  • Barbettes for main turrets: 250 mm (10 in) above upper deck; 200 mm (7.9 in) between main and upper decks; 40 mm (1.6 in) director tower communication[2]
  • Barbettes for secondary armament: 75 mm (3.0 in) above upper deck; 60 mm (2.4 in) director towers[2]
Notesall of the above characteristics are from a drawing dated 19 April 1940, with the exception of the armament; those are from a drawing done on 16 February 1940.

Design 1047, also known as Project 1047,[8] was a series of plans for a class of Dutch battlecruisers prior to the Second World War. These large capital ships were intended to counter the threat posed by Japanese aggression towards the Dutch colonies in the East Indies.

Dutch intelligence believed that if it came to war, the Imperial Japanese Navy would deploy its capital ships (aircraft carriers and battleships) against their counterparts of the United States Navy and the British Royal Navy. That would leave heavy and light cruisers, along with seaplane carriers, as the largest warships available for an advance into the East Indies.

To combat a force of these ships, in the 1930s the Koninklijke Marine (Royal Netherlands Navy) prepared designs for a new class of battlecruisers. Their work was shaped by the perceived need to fight their way through a fleet of those cruisers and smaller destroyers; the Dutch hoped that this would allow the battlecruisers to act as a fleet in being. However, the Dutch had never designed a modern capital ship, and this was reflected in a preliminary plan completed on 11 July 1939: it was missing many of the post-First World War advances in warship technology, and the armor protection was completely outmoded.

After an extended period of negotiations, Germany and the Netherlands reached an agreement where Germany would release plans and drawings based upon their ideas for a battlecruiser. In return, the Dutch would guarantee that all the required equipment would be ordered from German firms. With German assistance, a rough design was formulated by February 1940. A visit to Italy prompted a rethink of the internal layout, which led to a set of drawings dated 19 April 1940. This is the last known design produced prior to Germany's invasion and occupation of the Netherlands. Final plans for the ships were never completed, and the ships were never constructed.
