When most combat aircraft detect that they've been targeted by a guided missile, they try to protect themselves by firing flares or chaff to confuse the missile's guidance system. In the titanium-skinned SR-71 Blackbird, missile avoidance is much simpler: Just gun it. At top speeds of Mach 3.2, there isn't a missile in the sky that can catch the thing. And there's only one metal strong and light enough to handle those speeds without melting out of the sky: titanium.
It's the same metal that's the core of the beta titanium alloy in our Ultralite® Titanium sunglasses. Beta titanium adds small amounts of aluminum and vanadium to improve titanium's flexibility, while maintaining the metal's strength-to-weight ratio that is unmatched in the natural world.
This ultralight frame holds a pair of rimless TriLenium® polarized lenses, developed from original NASA optic technology, that works to enhance visual clarity and definition while protecting your eyes from blue light and 99.9% of damaging UVA and UVB radiation.
Together, the entire package comes in at just half an ounce.
