The LAFAYETTE SSBN-616 was laid down 17 January 1961 by Electric Boat Co., Division of General Dynamics, Groton, CN/USA and launched 8 May 1962. The Lafayette had her place in the Navy’s expanding “Polaris Fleet” during the 1960’s. While still in service in March 1991 the vessel was decommissioned on the August 12 of that year.
This kit offers a high grade of pre-fabrication and content.
The hull of the model is made of glass fiber reinforced (GR) Epoxy. The main hull consists of two parts, the bow and aft section which are combined with a bayonet lock ring made of alloy and sealed with an o-ring.
The rocket hatch section is also made of GR Epoxy and shows finely scribed detail.
Conning tower with periscope parts, rudders and dive planes are all cast in resin to allow easy assembly.
The inner section (so-called technical frame) is made of CNC cut PVC allowing easy and fast assembly. All parts have their set location and a very good fit. Furthermore, the frame is reinforced by alloy bars with threaded ends which are screwed against or into the CNC cut bulkheads.
The rear (main) bulk head is cast in 12 mm thick resin and incorporates all necessary connections for the screwed-on alloy bars, main drive as well as two water in-/outlets for the Piston Tank and the Pressure Switch.
The center of the inner section consists of a single Piston Tank type EA825-12 (825ml volume with AutoStop, 12V) which comes pre-mounted with the necessary bulkhead on each end.
The Piston Tank is controlled by the electronic switch unit CTS2 which is mounted directly on to the Piston Tank. The CTS2 incorporates a Pressure Switch as security device (located at the bow of the frame) which limits the maximum depth to about 1.8 meters. The UNI also features a second security device, the so-called “low battery monitor” which forces the model to emerge should the voltage of the battery drop below 9 Volt for longer than 6 seconds.
The 12 Volt drive of the Piston Tank runs smoothly and allows the tank to be flooded fully after 18 seconds.
The model has a 12 Volt direct drive motor. This is attached to a specially fabricated alloy mount which is fitted to the main bulk head and sealed with an o-ring. The coupling connecting the motor to the prop shaft (stainless steel) runs within this mount, closed-off by a shaft seal. The kit also includes a 6-blade scimitar prop made of brass.
This set-up allows a speed of up to 12 km/h (approx. 7.5 mph, submerged).
The kit comes with all necessary components, such as pre-cut tubes and rods as well as linkages, connectors, screws, nuts etc. as well as comprehensive building instructions in English supplemented by 3-D drawings a general plan.
All parts are packed in groups to their corresponding sections of the model.
