    Design Features. The Model 86 is a non-penetrating, environment without a lengthy stay on the surface. It is two-stage, modular, electro-optical sensor system, capable of a sector scan in less than two seconds, and a developed by Kollmorgen to replace conventional full circular scan in five to six seconds, when using a periscopes. The U.S. Navy version uses a modular hoist black-and-white camera. Automatic modes are mast, developed in cooperation with Italys Riva provided for programmed horizon and hemisphere Calzoni. The systems main components are the Sensor search, also contributing to the short above-surface time Unit, Rotation Unit, Mast Unit, Interface Electronics needed to establish a view of the area.

Electronic processing and storage of the and night viewing, and color television for daylight information make the use of the data more flexible in viewing. It has a built-in two-axis stabilization feature, terms of time and place, and the information can be intended to eliminate effects of the ships motion and enhanced for improved observation of details, if mast vibration.

    Program Review

    Background. While submarines above-water imaging satisfy selected visual requirements. These optronic requirements were traditionally met by optical periscopes (thus called for combining optics and periscopes from the early part of the 20thcentury until electronics) offer additional benefits, such as Image the 1970s, significant changes have taken place and Intensifiers, Low Light Level TVs, or IR cameras and a combinations of periscopes and electronic sensors now number of ESM and communications antennas.

The company also concluded that the itself. The most obvious is the elimination of the demands placed on a new generation of periscopes, in opening in the pressure hull required by the periscope terms of sensor integration, data accumulation, and shaft. Most discussions of submarine diving depth reduced exposure time, could best be met by adopting a focus on the strength of the pressure hull itself, while non-penetrating mast solution. This led to the the fact that the integrity of the penetration seals is also development of the Model 86 periscope, the first to a critical factor is often ignored. Seal integrity is combine viewing and electromagnetic sensors on a directly correlated to the diameter of the hole in single non-penetrating mast.

    Forecast Rationale

    As the threat profile for todays submarine forces adapts and, according to Kollmorgen, provides new tactical to changing times, Kollmorgens Non-Penetrating capabilities.

    Periscopes (NPPs) appear to be poised for increased Virginia class submarines are expected to be produced procurement over the next several years. Submarines along the following schedule; the first entered service in are expected to be increasingly used in shallow water 2004, and the following three boats will follow in 2006, special operations, such as deploying Navy SEALS for 2007, and 2008. There will then be a delay until the clandestine missions. The closer proximity to hostile maximum production rate kicks in, which should see territories makes use of the NPPs, with their advanced production increasing to two or even three boats per surveillance and electronic support measures (ESM) year. A total of up to 30 Virginia-class submarines are capabilities, even more beneficial. While NPP expected to be produced. production for the emerging fleet of U.S. Navy

An early version, the As the new-build submarine market outside the U.S. is Model 86 two-stage, modular, electro-optical sensor in something of a decline, and with little or no public system, offers thermal imaging for day and night source information on foreign military sales, this viewing, and color television for daylight viewing.
