The German multinational HDW has revoked a sub-construction contract it had concluded with the Hellenic Shipyard, for the "Poseidon" programme, which included the modernistion of the submarine "Okeanos" and the construction of another two 214-type subs for the Hellenic Navy.
A notification was provided by the German firm legal representative towards the defence ministry.

An announcement by the ministry later stated, among other things, that the interests of the country are fully safeguarded with law 3885/2010 and this development does not obstruct the delivery, according to the timetable agreed, of the three 214 type submarines that are ready at the shipyards -- the "Archimidis" programme.
