Abstract The attitude of the outer space regime is no doubt to the effect that the environment belongs to nobody (whether as a state or individual) but to everybody (mankind) to explore and use. Ordinarily, the provisions of the international space regimes on ownership of outer space seems convincing enough to conclude that there is absolute freedom to use outer space to ones unending satisfaction, as to justify the use of this pristine environment for military purpose by the super space actors. On further thought, it is a subject of doubt to spring up further probe into the certainty or absoluteness of such freedom given to man in his quest to exploit outer space. To this work, findings as to the true nature of the 'absoluteness of the freedom of exploration and use of outer space vis-à vis its use for military purpose and weaponisation is necessary in determining whether or not it is a matter of 'give and take' in other words, a restricted freedom. This paper would focus on the relevant international law on the use of outer space to determine whether the use is for military purpose, and can be allowed or not, in order to make proper recommendation on the findings.
