| Silvercrest Submarines Newsletter
( 2003 Part 2).
We have a wide range of submarines (big
and small) plus Rovs for sale and possible charter. Priced to
suit all budgets and tasks. Israeli Sub Dakar. Remember in our last newsletter the story about
the tragic loss of the Israeli submarine Dakar on her maiden voyage
in 1968, and the discovery by Nauticos Corp. 30 years later. The
Dakar was a WWII T-class boat, built by the British and sold to
the Israelis after modifications, upgrades, and sea trials. In
1968, the Dakar was en route to Haifa via Gibraltar on her maiden
voyage for delivery to the operational fleet. During this transit,
communications inexplicably ceased and the submarine disappeared.
Under contract for the Israeli Navy, Nauticos -- along with subcontractors
Williamson & Associates Inc. (Seattle, Washington) and Phoenix
International Inc. (Landover. Maryland) -- set out to find the
Dakar in May 1999. The submarine was found badly damaged and resting
at depth of 10,000 feet in the Mediterranean. Dear Alan Taurus Submarine. Our Taurus submarine (normally six man, depth
1000ft) has recently carried out diving operations at the South
African Navy base in Simonstown. In addition to the commercial,
salvage, and scientific research operations that this submersible
undertakes, Taurus is also designed to operate as a submarine
rescue vessel (DSRV). In the rescue mode DSRV Taurus can shuttle
twenty passengers at a time from a stranded military submarine.
Currently a number of NATO navies as well as the South African
navy are discussing this capability. Submersibles for sale. For sale in excellent condition, this four-
man (1000ft depth rated) submersible with diver lockout facility.
We also have immediately available a range of multi passenger
tourist submarines (ten to forty passenger). Small two / three

These systems were supplied to the Russian Navy as part of a major investment in submarine escape and rescue equipment, made in the wake of Russia's Kursk submarine disaster. The four LARS are self-contained, air-transportable modular systems mounted on an ISO container base, allowing for easy shipment and installation on vessels of opportunity. Ohio Class Submarines. Electric Boat Corp., Groton, Connecticut, was awarded a $38.3 million contract modification to exercise an option for the procurement and manufacturing of long-lead-time material for the conversion of Ohio-class SSBN submarines to Ohio-class SSGN submarines. The Naval Sea Systems Command, Washington, D.C., is the contracting activity. Raytheon Co., Marlborough, Massachusetts, was awarded a $24.5 million contract for procurement of the Advanced Communications Mast (ACM). The ACM is a super high frequency antenna system to be operated on the SSN-23 submarine. It consists of electronic control equipment located in the radio room and antenna/transmitter equipment located in the sail. The ACM must interface with existing submarine systems as well as unique data source equipment installed only on the SSN-23 submarine. Lockheed Martin Corp. Naval Electronics and Surveillance Systems, Manassas, Virginia, was awarded a $69.96 million contract modification to exercise an option for the Acoustics Rapid Commercial Off-the-Shelf Insertion (ARCI) sonar system. ARCI integrates and improves towed array, hull array, sphere array, and other ship sensor processing on SSN 688, SSN 688I, SSN 21, and SSBN 726 class submarines. Dual Deepworker submersibles for sale. This exciting package of dual (2) Deepworker submersibles is now available for sale. 
Each Deepworker is a one-man tetherless submersible capable of working in depths up to 2000ft.
Submersible pilots in the past have been constrained
to only piloting the vehicle and monitoring his systems, which
are critical tasks. Deepworker operators can be alleviated from
a number of these tasks due to technology, modernization and the
inherent ergonomic design of this particular vehicle. In this
design the pilot is seated upright. The view port is a 25" hemispherical
dome. The pilot can enter desired depth and heading data into
the PLC and Instruct the PLC to maintain that course, depth and
heading. The PLC will continue to perform that function until
cancelled by the pilot. The versatility of the PLC along with
the ancillary computer also allows for other capabilities such
as acoustic electronic communication of critical operational information
with the surface vessel. The submersible is outfitted with a six-function
manipulator. Additional hydraulic tooling is easily integrated
such as water jets, suctions, and guillotines. If necessary ,an
additional manipulator can be installed for specific dexterity
requirements. Submarine/Auv Autopilot. H Scientific Ltd. successfully commissioned its 3DMC autopilots on a manned submarine, on a fast RHIB (more than 30 knots), and on an airship. The firm's Dr. Henry Robinson said the firm's autopilot is "the world's first off-the-shelf autopilot for AUVs." The 3DMC, developed in collaboration with Chelsea Technologies Group (West Molesey, Surrey, U.K.), is designed to be applicable to a wide range of vehicles. Software configuration allows the autopilot to be connected to many different sensors and actuators. Recent trials illustrate the versatility of the autopilot, Robinson said, "working not only on such different vehicles in such different speed regimes, but also in different media, air, as well as surface and subsea. These successes demonstrated how effectively it can learn the characteristics of a new vehicle, typically in less than a minute." In each case the learning process worked first time, with no pre-tuning needed, he added. Visit the website at www.h-scientific.co.uk/ Marlin Building a new Submarine. A small specialist company is currently building
a diesel electric manned submarine. Classified as an American
Bureau of Shipping +A1 submersible, the Marlin AP6 will be a six-passenger,
18 tonne tourist submarine capable of diving to 302 meters depths.
Richard Dawson said the intention is to provide a specialized
service to enable interested tourists, scientists, and environmentalists
to observe a wider spectrum of marine life and seabed conditions.
The passenger section of the pressure hull will consist of two
intersecting transparent acrylic spheres, 1.85 meters inside diameter
and 100 millimeters thick. The passengers and crew will be treated
to a spectacular all round view previously enjoyed only by the
most advanced research submersibles, he said. The vessel will
be the first ever to employ this twin sphere geometry. Construction
is currently well advanced, and delivery of the pressure hull
components (the only items that are not made in-house) is expected
early in 2003. The craft is due for completion in early summer
2003, and after the completion of the sea trials off Plymouth
in Devon, will be available for charter. Autosub for the Antartic. Dr. David Vaughn of the British Antarctica Survey will be using Southampton Oceanography Centre's Autosub to investigate the cavity under Pine Island Glacier, one of the fastest Antarctic ice streams. Satellites show that the grounded portion of the glacier thinned by up to 1.6 meters per year from 1992 to 1999. A large iceberg, 42 by 17 kilometers, broke off the Pine Island Glacier in early November 2001. Ice shelves are the floating edges of the ice sheets that cover Greenland and Antarctica. These shelves are involved in the waxing and waning of the ice sheets as climate changes. They contain over 70% of the world's freshwater -- enough to increase sea level by 80 meters if they melted entirely. But what takes place in the vast water cavities beneath ice shelves -- which can be a thousand meters thick -- is largely unknown. The autonomous underwater vehicle Autosub's unique capabilities will allow Vaughn to make the first direct measurements of the newly exposed bed of a retreating ice stream. The AUV will be diving to depths below 1,000 meters to gain access to the glacier cavity. On previous research missions in the open ocean, Autosub has been programmed to surface if she gets into difficulties. The engineering team at SOC designed a completely novel navigation system to overcome the dangers of working in an enclosed space. This research project is the first in the Autosub Under Ice Program funded by the U.K. Natural Environment Research Council.www.soc.soton.ac.uk/ Two Rov's for Immediate Sale. a) Hyball Rov available for sale in excellent

buy, a bargain. Rus 6000 submersibles. RUS, a 6000m submersible, built by Malachite for the Ministry of Geology in Russia. Uses silver zinc batteries, Russian manufactured syntactic foam, and a welded titanium hull. Malachite has considerable experience in welding thick titanium. Two submarines were built in Russia in 1991. Now in operation supporting scientific research. Depth 6000m. Crew 2/3. SilverFish 4000 Submersible. The SilverFish 4000 is a complete new build submersible being constructed in Europe, and designed by Ramsey Martin, Organisations interested in purchasing this submersible will have the opportunity to customise the unit to meet their specific operational requirements. The titanium sphere has now been constructed and tested for an operational depth of 4000m (12,800ft). Internal and external design is currently being undertaken prior to final outfitting. The basic design of this submersible offers the maximum adaptability to optimise the configuration of the vehicle for the roles required by the client. As a very deep diving one atmosphere submersible, the main tasks envisaged will be seabed search and survey, scientific research, and military applications. Viking Submarine Project Enters New Phase. The Viking Project has now reached the tendering phase. The Swedish, Norwegian and Danish navies - have recently submitted specifications that will form the basis of this tender. The Viking Submarine Corporation is a joint venture between Kockums AB of Sweden, Kongsberg Defence & Aerospace of Norway and Odense Staalskibsvaerft A/S of Denmark. The company will now submit a tender for project planning, which will form the basis for decision regarding design and construction of ten submarines: four each for Denmark and Norway, and two for Sweden. The submarines will be designed to operate under widely differing conditions, in terms of range, operational duration and deep-diving capability. A document has been drafted outlining the joint specifications of participating countries, covering the special requirements of each country. This is made possible by adopting a joint basic design that is sufficiently flexible to allow for modifications and add-on capabilities as required. This basic design specifies a submarine that combines completely air-independent propulsion with a substantial punch and extreme efficiency. The Viking class submarines will offer significant advances in stealth capability and a dramatic improvement in the surveillance function, featuring advanced sonars. The Norwegian version, with a mission profile involving extended periods on the surface, covering considerable distances, will be fitted with a diesel as well as AIP propulsion system. Kittredege Submarine for sale. We have two Kittredge submarines for sale( operating depth 350ft and 600ft). These are small one/two man units that are great fun and very easy to operate and maintain.
