Another iconic sub located deep off Hawaii

What has been described as one of the world's “top 10 iconic mysterious shipwrecks”, the WW2 submarine USS S-28, has been located off Oahu, Hawaii at a depth of 2.6km.

The sub was found in September by an expedition headed by US robotics expert Tim Taylor, who runs Tiburon Subsea, and the announcement comes hot on the heels of that of another iconic submarine found in that month, HMAS AE1, as reported on Divernet.

Just as the AE1 was considered one of Australia’s most significant war casualties, in that case of WW1, the diesel submarine S-28 has been described as the most important lost US WW2 vessel in the central Pacific.

S-28 was laid down shortly after WW1 and launched in 1922.

She is credited with the sinking of one Japanese ship during her WW2 service, but sank in unexplained circumstances on 4 July, 1944 with her crew of 49.

Based on preliminary video and other documentation, Taylor’s team has speculated that the submarine sustained a hull failure that resulted in the eventual separation of the bow, causing a near-instant loss.

“The current mapping and filming of the wreck by the discovery team is yielding valuable information that can help determine and possibly solve the cause of the sinking,” says Tiburon Subsea, which is sharing its data with US Navy Heritage Command and families of the entombed sailors.

New York-based Tiburon Subsea hires out autonomous underwater vehicles (AUVs) and other underwater technology such as imaging equipment.

AUVs were used for the initial search for S-28 and ROVs then took over to film and photograph the wreck-site.

The expedition carried the Explorers Club flag, and S-28 is the third WW2 submarine to be located by Taylor's team.

Do you need to be fit to dive?

Adventurer, technical diver, stuntman, climber and all-round Action Man Andy Torbet knows a thing or two about keeping fit. Here he gives some basic advice to help us all get back into shape for when we can hit the water again.

Ship shape

The skipper promised me a wreck, so it must be down here somewhere. If the vis was better, I might even be able to see it.

Things fall apart

I can’t quite understand it. How did that happen? Every item of my scuba kit was fine when I put it away.

Free and squeezy

Freediving – it’s basically snorkelling with good PR. It involves holding your breath, often to the point of semi-suffocation. What’s so free about that?
