The SA Navy has dismissed claims that one of the three German submarines bought in the arms deal is a "dud", and says the SAS Manthatisi S101 is in Simon's Town naval drydock as part of "normal naval procedure".

The navy has also denied claims that submariners were "too afraid" to do the first safety dive on another of the submarines, SAS Queen Modjadji S103, saying it was standard procedure that the contractors' crew completed sea acceptance trials prior to the handover of the vessels to the purchaser.

SAS Queen Modjadji skipper, Commander Andrew Souma, said yesterday that the South African crew had since taken the vessel to its dive limit "hundreds of times".

"There has been no drama with this boat," Souma said.

The navy was reacting to claims in the Sunday Times that SAS Manthatisi S101 had been "plagued by defects" and had spent most of the past six months out of water.

The article said problems on the submarine included defects in the hull valve, an implosion of the air intake for diesel on its maiden voyage and an implosion on board when the submarine had been connected to an onshore power supply, contrary to correct procedure.

Rear Admiral Hanno Teuteberg, director of fleet force preparedness, said: "SAS Manthatisi is not a dud. We said we would run two and have one in reserve."

Teuteberg was asked to comment on the claims yesterday during a meeting in Simon's Town of the directors-general of the justice, crime prevention and security (JCPS) cluster and the SA Police Service Sea Borderline Control Unit. The navy is part of the JCPS.

Teutenberg said it was normal naval procedure to rotate submarines, which was "the way navies do things". While two were being deployed, the third was used for on-board training, which did away with the need to send crew to Germany to be trained. The vessel would not come back into operation until around this time next year.

"There has been talk of explosions. There was never any explosion on any South African submarine."

Reporters at the meeting were given a press statement issued by the Department of Defence on Friday that said the SAS Manthatisi had initially had hull valve problems that had been rectified under the manufacturer's warranty.

Naval staff said it was standard practice to push a new vessel to its limit under warranty so defects could be detected and rectified.

During such testing in Norwegian waters, the housing for the air- intake for the diesel had imploded and had been widely reported at the time. The statement said the German navy had congratulated the SA Navy at the time for its "prompt reaction and expertise displayed during the incident". There had not been any implosion during a battery change.

Teuteberg said South African submariners were highly trained and "some of the best in the world".

The statement said that, because South Africa had some of the best naval training in the world, it was losing highly qualified staff to the private sector and countries overseas. The navy had taken steps to address the loss of skilled staff. These included recruitment and submissions for more pay in the form of allowances.
