The intensification of the air threat resulting from the emergence of hypersonic weapons in the immediate vicinity of Poland has become a significant challenge for the Polish armed forces, including anti-aircraft defense. The capabilities of the new type of weapon determine not only the need to modernize and acquire systems designed to engage aerial targets, but also the command and control systems that control them. Due to the nature and the limited scope of the article, the deliberations presented in it are generalized results of a research on the scale of the threat posed by hypersonic weapons in the airspace and the need to modernize anti-aircraft defense command and control subsystems, which may be involved in combating them as part of the national air defense system. The presented conclusions also concern the problems of multiplying the current level of automation of the command and control subsystem. This is related to the need for the effectiveness of the military decision-making process as well as uninterrupted and efficient cooperation with the national and allied elements of the air reconnaissance and air defense assets subsystems, including the components of missile defense, which is predestined to engage hypersonic weapons.

The project presented in this article, which consists in designing and launching a three-stage suborbital rocket with a 40 kg payload covers the subjects of the rapid development of a multi-stage proof-of-concept vehicle with a limited time to deploy. These finite resources and a negligible percentage of the technology available tested in-house in advance led to the implementation of chosen, well-known industrial solutions into the concept for a winning strategy. This paper presents the recent achievements and lessons learned from the production phase of the components, namely: the rocket motor, control section compartment, guidance and navigation bay, together with recent achievements and future challenges. This set of components, derived from the project, will fill the gap in the technological chain for future Polish launchers and munition. The three-stage suborbital rocket development project is divided into three phases, which will last a total of three years. The first phase is the conceptual design stage, along with laboratory tests of solutions and subsystems used in the rocket. The second phase consists in flight tests for individual stages, together with the decisive flight of a three-stage rocket made to reach the Kármán line. The final stage involves the commercialization of the developed technology and the creation of a service for carrying research loads of up to 40 kg. The project is valued at approximately USD 5 million. The project is co-financed by the National Centre for Research and Development (NCRD) as part of dedicated support for the Polish space industry.
