  • The Naval Ocean Systems Center (NOSC) is now using Spectra® fibers for reinforced composites in the fairing—or hydrodynamic hull— and in the internal mounting structure of its unmanned submarines, which are technically called Advanced Underwater Search System Vehicles (AUSS).

    Spectra fibers, engineered by Allied- Signal Inc., provide unique combination of a high strength-toweight ratio and minimal signal distortion for undersea supplications.

    Pound for pound, Spectra fibers are 10 times stronger than steel. And, its near-zero dielectric constant permits excellent signal transparency.

    In addition, Spectra fibers exhibit outstanding chemical/abrasion resistance and low moisture regain.

    Other undersea applications being considered or now utilizing Spectra composites in structural support systems include: unmanned submarines and submersible robots used for mine detection, sea floor mapping, geological testing and photography, plus vessel recovery equipment.
