Когда тактика осады стала неотъемлемым условием успеха в войне, генералы перед инженерами и учеными поставили задачу разработать тактику, прорыва обороны и блокады города с помощью фокусов и обмана. Это увлекательное исследование отслеживает изменения в тактике осады от Древней Персии (6 веке до н. э.) до осад, осуществляемых Римом 2-й век до нашей эры), описывая широкий спектр оборудования и техники, которые использовались в этот период.

On 22nd-27th August 1995, the aircraft was in the static display at the M AKS-95 airshow in Zhukovsky. In order to calculate trajectory guidance algorithms for the space shuttle, Lll converted a MiG-25PU 'Blue 22' into the MiG-25PU-SOTN (Samolyot Optiko-Televizionnovo Nablydeniya - optical/TV surveillance aircraft). The aircraft's purposes included: - advanced research of trajectory guidance algorithms for the space shuttle at altitudes below 20,000m (65,616ft) as part of the shuttle's total in-flight simulation complex.
As far back as the early 1960s, a group of engine designers led by Shukhov and Rotmistrov proposed a comprehensive upgrade of the R15B-300 turbojet. The idea materialised as the uprated R15BF2-300, Izdelye 65M. The improvement in performance was achieved by adding a compressor stage and increasing the combustion chamber and turbine temperatures. 75). The two engines were perfectly interchangeable, having identical dimensions and mount- ings. Providing the airframe was made more heat-resistant (that is, because of the higher turbine temperature), the new engines offered a substantial increase in rate of climb, ceiling, range and speed (up to 3,500km/h, or 2,187mph).
