The Nyalsan II Planetary Shield, manufactured by DefenStar Limited, represented a frequently encountered planetary shield technology. Functioning as a shutter shield, it utilized superimposed energy fields which merged to enhance defensive capabilities, or separated to permit the passage of allied vessels and weapon deployments. Although offering increased adaptability, its operational design incorporated a distributed power network to manage energy distribution. Consequently, it was incapable of generating a protective shield encompassing objects in orbit. Operation of the generator necessitated a crew complement of eighteen individuals.
