Abstract
A method for constructing a ballistic resistant tower entails forming a tower ring for a ballistic resistant tower and welding a ballistic resistant stub to a structural ring on a ballistic resistant enclosure. The enclosure includes a hatch to allow entry into the enclosure. An embedment ring with perforations is constructed so that the ring can support a dynamic load and an impulse load of at least 24 psi for 5 milliseconds. The embedment ring is secured to a foundation and one or more tower rings are secured to the embedment ring using a slip ring. The slip ring ensures that the alignment of the tower ring with the embedment ring is correct. The method ends by slipping the ballistic resistant stub into the interior side and the upper end of the tower ring and welding the ballistic resistant stub to the interior side of the tower ring.
