Marine products
BAE Systems' glass-clad polycarbonate products are constructed using polyurethane high-adhesion bonding layers to form a multiply composite laminate.
The glass and polycarbonate composite laminate is superior to single material glazing concepts, and provides three primary benefits:
- Up to 60 percent reduction in thickness and weight compared to conventional glass and air gap security systems
- Increased ballistic tolerance
- Structural integrity of polycarbonate with the weathering, abrasion, chemical, and flame resistance of glass
ARMOR WINDOW SYSTEMS
BAE Systems’ armor windows are composite laminates of polycarbonate, glass, and polyurethane, and are 40 to 60 percent lighter and thinner than conventional glass designs. Multiple impact ballistic tolerance ranges from 17 gr. fragmentation to 20mm FSP, and from .22 caliber handgun to in excess of .50 caliber armor piercing protection. Window configurations resistant to explosion shrapnel and blast overpressure exceeding 200 psi are also available. Armor window systems are non-spalling and provide:
- Ballistic protection and tighter impact patterns
- Lighter weight
- Improved optical characteristics
- Higher visible light and infrared transmission
- All climate reliability
ELECTRONIC SHIELDING
Electrical interference and electronic threat protection is achieved by using a variety of transparent metallic coating systems within the window. A significant range of frequencies can be attenuated to prevent instrument interference or damage, electronic eavesdropping, and jamming. Effective shielding against threats, including RFI, EMI EMP, NEMP, and microwaves, has been demonstrated in excess of 20 GHz. Similar transparent coatings with controlled resistivities can also promote RCS reductions. Transparent metallic coating systems provide:
- Maximum shielding effectiveness
- No target resolution loss
- High visible light transmission
- Compatibility with night vision goggles and infrared navigation aids
- No adverse affect on window optical quality or color recognition
OPTICAL SHIELDING
Optical threats such as nuclear flash, and the thermal effects of heat pulse, infrared, and laser, can be effectively attenuated or filtered in nominal window sizes through the use of special transparent coatings
SUPERIOR OPTICAL QUALITY
Armor window system optical properties include higher light transmission, excellent visual clarity, and aircraft quality optics. Optical distortion and deviation are minimal, even in armor thickness exceeding 2 inches, where displacement is typically less than 3 mins. of arc.
ALL-WEATHER VISION
Laminated glass fixed windows and sacrificial panes are electrically heated for continuous, all-weather vision. When powered, ice, frost, snow, and condensation are removed within minutes. This anti-ice/fog capability is achieved through the application of a thin, transparent, metallic coating to provide electrical heating of the laminate.
TOTAL CAPABILITY
Available in performance ranges from 24 volt inputs to 440 volt marine requirements.
CLEAR VISION
The windows feature continuous, high-light transmission clear coatings without frit lines or embedded wires that would obscure vision.
TEMPERATURE AND POWER CONTROL
Sensing devices can be incorporated within the window to provide precise temperature control and power regulation. These devices are silent, reliable, and more energy efficient than warm air blowers, providing a cost-effective solution for new construction or retrofit requirements.
UNIVERSAL APPLICATIONS
The system can be incorporated within any of BAE Systems’ laminated windows, including Armor. Meets or exceeds MIL-W-18445.
