During the Siege of Port Arthur by the Imperial Japanese, the Russian defenders sought innovative ways to turn the tables on the enemy. And a hand built submarine seemed like the answer! A strong parallel to the Confederate defenders of Charleston can be made. Submarines, at the time uncertain weapons of war, represented a relatively cheap way to locally produce craft which could take on the enemy blockade. Submarines were however the preserve of creative and often eccentric engineers and although the Russian Navy tolerated the construction of the 25 ton Naletova submarine, they were reluctant to fund it. So it was built as a private enterprise by its designer. Read More >....

Cutaway of Narco submarine
The illustration shows the 24m (60ft) semi-submersible ‘snorkel sub’ discovered on 20th Oct 2013 in the jungle on the Ecuador/Colombian border. The design is innovative and unusual, and is one of only two true semi-submersibles captured. The vast majority of “narco subs” are Low Profile Vessels (LPVs) which cannot fully submerge. This boat cannot run fully submerged either and requires the snort mast to be above the surface. The hull is below the surface however and depth and trim can be regulated by flooding seawater into the ballast tanks. It can carry up to 8 tons of cocaine for thousands of miles, making trips from Colombia to Mexico or beyond. (see previous COVERT SHORES article)

Iranian Revolutionary Guards acquire 2 US Navy Riverine Command Boats
UPDATED: The ‘acquisition’ was short lived. Iran has released the two boats along with the crew. It remains to be seen whether the Iranian Revolutionary Guard’s navy (IRGC-N) will clone the Riverine Command Boat (RCB), a variant of the Swedish CB90 family. My guess is that it won’t be long before we see the Iranian version of the classic Combat Boat 90 (CB90), “100% developed in Iran”, being paraded by the IRGC-N. Read More >....
Unbuilt project MSV-75 Special Forces submarine
The 1970s saw a resurgent German submarine (U-boot) industry, and the start of a period when they would dominate the export market. Typical German submarines, such as the ubiquitous Type-209, were relatively small diesel-electric boats but packed a big punch. Several other designs were even smaller however, and aimed at the Special Forces and special operations market which was at the time dominated by Italian firm Cos.Mo.S. One of the designs on offer was the Thyssen Nordseewerke MSV-75 (Multipurpose Submersible Vessel) ..... Read More >....

Quiz - Combat Boats
Ever since the Swedish Combat Boat 90 (CB-90) hit the scene, the world of assault boats (fast landing craft etc) has not been the same. The CB90 set new standards of speed, versatility, accommodation, robustness and, importantly, style. Since then many firms have built craft in a similar vein. In fact, most are almost indistinguishable, which is what this quiz is about. Identify which CB90 clone is which.

Book Review - Commander Crabb - What Really Happened
The mysterious disappearance of Commander Lionel Crabb while conducting a covert underwater examination of a Soviet cruiser has gripped the public’s imagination for years. And the diving community too. An eccentric character, the uncertain circumstances, a botched MI6 cover-up and political embarrassment on an international scale came together in the perfect Cold War mystery. Previous books and media have almost exclusively focused on the most sensationalist and farfetched versions of the tale, including Conspiracy Theories. So this book, researched and authored by the Chairman of the Historical Diving Society, is a breath of fresh air. Read More >....
