Radetzky class Frigates (1857)

Austrian Navy Austrian Navy 1854-88: SMS Radetzky, Adria, Donau


In 1852, the Austro-Hungarian Navy’s high command proposed the construction of a modern steam frigate, to be declined into a class of three vessels, the first built in Britain and the two others in Austria, bringing with it valuable technological and engineering lessons. SMS Radetzky and her sister ships Donau and Adria were modern frigates of the Austro-Hungarian Navy, a bit wider and shorter than the previous SMS Novara (1850). They were not built in Austria, which lacked large facilities and expertise to make them, but were ordered to Money, Wigram & Sons of London for the lead vessel.
The lead ship was named after nobleman and field marshal Joseph Radetzky von Radetz and launched in 1854. She participated in the Battle of Heligoland during the Second Schleswig War in 1864 and the Battle of Lissa, but sank due to the explosion of her powder magazine off Vis, Croatia.

The construction of the SMS Adria ordered at the San Marco Shipyard (Tonello brothers, Muggia) started when laid down in 1855. She was launched on 24 November 1856 in presence of Emperor Franz Joseph I and his wife Empress Elisabeth, from the corvette Kaiserin Elisabeth. She was completed in 1857 and entered active service in the k.u.k. Kriegsmarine on 1 July. Like her sisters she had a three square-rigging, bowsprit and mainsail for 2,711 m² total of sail area. She was propelled by the same horizontal cylinder drive unit on three shafts, working at 300 PSi for a top speed of 9.5 knots (17.59 km/h). She was a bit larger than the lead ship at 2,198 tons standard and 2,430 GRT, 64.02 m long for 13.09 m in beam and 5.2 m of draft. Her crew comprised 368 officers and ratings.
Her armament when completed was four 60-pdr howitzers, twenty-four 30-pdr mortars, three breech-loading 24-pdr pieces, and two swivel-mounted 2-pdr for close quarters, plus ample provision of rifles and grenades.

As for SMS Donau, she was also ordered at the San Marco Shipyard, of Tonello bros. in 1853, but laid down in 1855 at the “Squero Cadetti”. She was launched on 20 November 1856 in the presence of Archduke Maximilian of Habsburg. Completed in 1857 she was soon under service. Her specifications were the same as SMS Adria, but with a 2,334 tons displacement, 3 shafts and the same steam engine capable of 9 knots (16.67 km/h) and a Crew of 368. Her armament was the same until upgraded in 1864 (see below).

SMS Radetzky

The construction of SMS Graf Radetsky from the British shipyard Money, Wigram & Sons in London in 1852, was followed by a launch on 13 April 1854, and she entered service in the k.u.k. Kriegsmarine in September 1854, arriving in Trieste on 11 November. She was in maintenance in 1859 and by the autumn of 1860, under command of Lieutenant Commander Wilhelm von Tegetthoff she sailed in Syrian waters.

Later she took part in the third Italian War of Independence, under command of Captain Josef von Aurnhammer, assigned to the 2nd Division (Anton von Petz) of von Tegetthoff’s naval squadron and took part in the battle of Lissa in 1866 (all three of the class took part). She was engaged against Italian units from RADM Admiral Giovanni Vacca’s division. She survived the battle with very few casulaties and returned to her peactime duties.
She was the first of the class to be lost, due to an internal explosion at 10:00 on 20 February 1869, off Lissa Island, killing 344 of her crew of 368. Her wreck was rediscovered by Croatian navy minesweepers HRM Korčula in 2014, under 90 m near the island of Vis.

SMS Adria

On July 20, 1857, Adria left the harbor of Trieste for the squadron’s summer maneuvers, stopping at Brindisi, Naples, Livorno, Alexandria, Corfu, and back to Fiume on 29 september.

In 1861, she took part in the blockade of Durazzo, and in 1863 became a training ship for naval cadets.
In 1866, she was involved in the Third Italian War of Independence assigned to the Second Division, under command of Commodore Anton von Petz and Rear Admiral Wilhelm von Tegetthoff’s Naval Squadron. On July 20, under command of Fregattenkapitän Adolf Daufalik she took part in the battle of Lissa, firing 221 shots and receivinh 27 hits in return for the loss of only two crewmen, three more seriously injured, two 2 lightly wounded.

On 1 October 1868, she returned to her cadet instructional duties and made a cruise with the Marineakademie in Rijeka.
