Existing ceramic technology is analyzed for producing high-speed zenith guided rocket antenna radomes made of glass ceramic OTM-357. This is the main production operations, and their disadvantages are noted. Prospects are considered for modernizing the technology.Analysis of the synthesis of glass ceramic materials, presented in part 3 of this work, points to rapidly developing new methods, and new areas in the field of sitall technology. In the former USSR production of radioparent radomes from sitalls for rockets, created by order of the Ministry of Defence, were concentrated in single enterprises, which remained outside Russia. In addition, materials developed in the 1960 -1970s, including sitalls (AS 418, AS370, AS 023, etc.) are ageing and do not relate to new specifications laid down for radomes. In this connection there is evidently a requirement for performing research in the area of synthesizing new materials, with a capacity to provide import substitution of sitall radomes for making up Russian military technology, and the possibility of creating radomes for future rockets. In addition, the dependence on an overseas state in the manufacture of military products could cause unjustifiable damage to the military capabilities of the country and the export of military products from Russia.In the Obninsk Scientific and Production Enterprise Tekhnologiya effective technology has been proposed, scientifically substantiated, and subsequently implemented for synthesis of glass ceramic materials [1 -4], combining elements of ceramic and glass technology and serving as a basis for creating a new scientific area in the field of synthesizing glass ceramic materials.The main practical results of ten years of research consist of creating a new class of glass ceramic materials (a series of materials of the type OTM-357) and development of technology for manufacturing more than ten forms of rocket radomes ( Fig. 1), providing solution of important state problems, i.e. import substitution of sitall radomes for the completion of contemporary and future rocket technology. The importance and state significance of work in this field is confirmed by valuable financing from the Russian budget, and also the situation that the personnel of FGUP ONPP Tekhnologiya, directly taking part in the work of this development, have been awarded prizes from the RF government
