basic doctrine of the indian air force CHARACTERISTICS OF AIR POWER Air power exploits the vertical dimension and its nature is a function of the physical attributes of this dimension. The vertical dimension is exploited not only as a medium of transit, but also for manoeuvre, concealment, surprise and a host of other factors. An understanding of the distinct characteristics and limitations of the vertical dimension is essential to enable optimal exploitation of air power. These distinct physical attributes make for the distinct characteristics of air power. The core characteristics of air power are speed, flexibility, reach and elevation. These attributes are shared with the space environment, but in a different way, and on an entirely different scale; consequently, the unique features of space power are dealt with separately. These core characteristics make up the larger sub-set of characteristics which are as follows:  Flexibility & Versatility. The first set of characteristics of air power can be placed under the heading of flexibility and versatility. Flexibility consists of the ability to use combat power in ways suited to the situation while versatility implies that the same weapons platform can be used for a variety of missions. For example, a modern multi-role combat aircraft like the SU-30 MKI can be used for almost all roles that are assigned to modern fighter aircraft. Similarly, most modern transport aircraft like the C-130 J Hercules and helicopters like the Mi-17 V5 are designed as multi-role platforms. Flexibility and versatility have a special relevance for the IAF as aircraft and equipment costs are rising exponentially, and there is need to extract the maximum value for taxpayers’ money. In short, the IAF cannot afford to operate aircraft, which can only be employed at one level of conflict or for one type of role.  Mobility. The unique ability of aircraft to manoeuvre freely and swiftly in three dimensions gives them the speed and the range to apply military power where needed over a very large area. Mobility has particular relevance in joint operations where forces need to be moved and re-supplied at short notice within and between theatres. 18
