Circumstances of Loss Details

-----------------------------

The German battlecruiser DERFFLINGER was scuttled in Scapa Flow.

Surveying Details

-----------------------------

8 April 1936. The wreck was sold to Metal Industries Ltd.

14 June 1938. Salvage has commenced and a temporary Notice to Mariners has been issued 1139/38.

Report from Navy Base Invergordon.

25 July 1938. The air lock fitted is now marked by flashing light.

Report from Naby Base Invergordon.

6 November 1939. The wreck was raised from 58 53 00N, 003 12 00W, approximately, and moved to 58 51 51N, 003 12 15W. It lay, bottom up, in this position all through World War II and was eventually taken to Rosyth for breaking in 1946.

Hydrographic Office, 1995.

Length: 689ft (210m)

Beam: 95ft 3ins (29m)

Draught: 28ft (8.5m)

Displacement: 26180/28000 tons [also cited as 26180/28000 and as 26,600]

Propulsion: steam turbines; 4 propellers; 85,000 hp; 27/28 kts

Armament: 8 x 30.5cm (12ins: 50 cal: twin turrets); 12 or 14 x 15cm (5.9ins: 45 cal: single mountings); 4 x 8.8cm AA (3.5ins: 45 cal: single mountings); 4 x 50cm (19.7ins) torpedo tubes [Tertiary armament cited by Jane as 12 x 24pdr with no AA armament fitted: this remains unverified].

Armour: belt 11.75ins (298mm); turrets 10.75ins (273mm)

Complement: 1112/1214

This battlecruiser was the first-built and name-ship of the three-strong Derfflinger class, and was built by Blohm and Voss at Hamburg, being laid down in March 1912, launched on 12 July 1913 and completed in July 1914. At the time of their construction, the ships of this class were considered the best battlecruisers in the world, having 12-inch guns in superimposed turrets, tripod masts and a flush-decked design.

She took part in the bombardments of Scarborough and Whitby (1914) and fought at the battles of Dogger Bank (January 1915) and Jutland (May 1916). The ship was instrumental in the destruction of HMS Queen Mary at the latter event, but suffered severe damage aft.

The ship was raised inverted from a depth of 45m by Metal Industries in August (also cited as spring) 1939, being both the deepest ship raised and the last to be raised intact. This operation was particularly difficult as the wreck had a significant list and had sunk into the mud. The wreck remained intact at Scapa (moored off Rysa Little) for want of a scrapping dock until after the Second World War, being taken in 1946 to be broken up at Faslane (also cited as Roseneath or Rosneath) on the Clyde. No other ship has ever been kept upside-down for so long a period. The passage to the Clyde took place in a dry dock, still inverted and with her turrets in place.

The location formerly cited for this vessel (N58 51.85 W3 12.25: ND 3055 9800) is evidently an intermediate position, presumably that where the inverted wreck was held between 1939 and 1946. It falls in an charted depth of about 15m and within Rysa Sound [name centred ND 305 978] to the W of Rysa Little. The original location of the ship is cited by the Hydrographic Office [1995] as N58 53.00 W3 12.00 [HY 3083 0012]. This location falls about 0.8nm WSW of Calf of Cava light. The charted depth is about 41m and no seabed is specified, but it is within an extensive area of foul ground

This ship may be considered as falling within the Bring Deeps group of heavy ships, which were scuttled within the area defined by Holm of Houton [name: HY 315 029], Calf of Cava [name: HY 322 006] and Green Head (Hoy) [name: ND 303 993].

Bring Deeps may be understood as a south-eastwards extension of Hoy Sound. It has a generally flat bottom at a charted depth of between 35 and 50m; the seabed type is defined sparingly but is apparently sandy. An area of spoil ground is noted around N58 53.9 W3 12.2 [HY 30 01], and may attest to the former presence of the High Seas Fleet.

HO Chart 35 (1980, revised 1991).

This vessel is considered a 'casualty' rather than a craft on account of its successful salvage, the available evidence being written rather than material. In the absence of diver survey, however, artifacts, fittings and, possibly, structural elements may survive on or in the seabed at the location of scuttling. Depressions in the seabed may also represent the locations of the turrets or superstructure.

Activities

Multi Beam Sonar Scan (16 October 2006 - 20 October 2006)

Multibeam sonar survey on board MV Anglia Sovereign recorded the remains of the salvage sites of the German High Seas Fleet to the west of Cava. Sonar survey recorded (anomaly 14) a significant depression in the seabed at a depth of 43m, at location UTM 30 N (WGS 84) X: 488479.63; Y 6527091.66. The site was interpreted as the salvage site of Sms Prinzregent Luitpold.

Side Scan Sonar Survey (4 April 2017)

Side scan sonar survey provided an overview of the final scuttled location and salvage area of the battlecruiser Sms Derfflinger. The following anomalies were identified.

All locations given to UTM 30 N (WGS84 datum).

(SS050) X: 488481; Y 6527063. Tripod mast.

(SS051) X: 488513; Y 6527040. Mast

(SS052) X: 488436; Y 6527099. Part of Derfflinger main site.

Information from ORCA Marine, University of the Highlands and Islands Archaeology Institute and SULA Diving April 2017

Multi Beam Sonar Scan (January 2017)

Diver inspection (2013) and multibeam sonar survey in January 2017 recorded a deep seabed depression and debris associated with the scuttling and primary salvage of Sms Derfflinger at this location by Metal Industries Ltd in 1939. The main features of wreckage lie to the south of the seabed depression caused by the hull. Moving from west to east are the remains of the two legs of the tripod mast, the southerly leg leading to a small searchlight platform. A diesel boat engine lies on the seabed. Further to the east still are the missing central leg of the tripod mast, and remains of the ship’s mainmast with an open platform and crow’s nest.

Diver Inspection (28 July 2017 - 6 November 2018)

A shallow depression orientated in a WNW to ESE direction appears in side scan and multibeam sonar data at the primary salvage site of Sms Derfflinger. The following sidescan contacts from the salvage sites phase 1 project at the north west side of the site were ground-truthed by divers or remote video in November 2018. The remains probably originate from the initial blasting of the tripod and aft masts following the raising of Derfflinger from the seabed in July 1939. SS050 was the forward tripod mast, with remains of searchlight platforms; two legs; third leg and spotting top missing. SS051 was interpreted as the Derfflinger aft mast and spotting top, as well as the missing third leg from the forward tripod mast.

Information from ORCA Marine, University of the Highlands and Islands Archaeology Institute and SULA Diving January 2019

Remote Operated Vehicle Survey (28 July 2017)

Remote Operated Vehicle (ROV) inspection of anomalies detected in the phase 1 salvage sites project (2017) identified the following features at the eastern side of the primary salvage site for SMS Derfflinger where the vessel was raised by Metal Industries on 25 July 1939 before moving to the east side of Rysa for clearance work.

All locations given to UTM 30 N (WGS84 datum).

(SS122) X: 488602 Y: 6527124. A large Danforth-type anchor located around 100m to the north east of the main seabed depression left by the hull of Derfflinger.

Nearby to the north west there was a concrete block probably used in salvage operations, and a torpedo mast. SS055 (see salvage sites phase 1) was verified , not as part of the aft mast but as one leg of the forward tripod mast. To the north west of this was a large diesel engine probably from one of the large diesel boats kept on the deck of Derfflinger.
