To lie down, the animal kneels on its front legs and then lowers the rest of its body. To get back up, it first gets on its knees and spreads its hind legs to raise its hindquarters.

Giraffe radar radar—three land-based systems (Giraffe 1X, Giraffe 4A and Giraffe 8A) and two naval variants (Sea Giraffe 1X and Sea Giraffe 4A). At the top end of the range is the Giraffe 8A, a long-range IEEE S-band (NATO E/F) 3D sensor that can be produced in fixed, transportable and fully mobile configurations. Intended primarily for remote operation as part of an integrated air defence network, Giraffe 8A can also be operated locally. It has an instrumented range of 470 km and an altitude capability of more than 40,000m, bringing true long-range air defence capability to the Saab radar family for the
