B. RAIDS 7. Airborne raids on Iceland (c) are considered unlikely. Aircraft would be operating at extreme range, and the country is not suitable for an airborne landing. Seaborne raids with the object of destroying important facilities are also unlikely, as they would be vulnerable to attacks on passage, and to shore based aircraft and coast defences on arrival off Iceland (c). The results of such raids would be unlikely to compensate for the risks involved. C. BOMBARDMENT BY NAVAL FORCES 8. Bombardment by Naval Forces is considered unlikely, owing to the vulnerability of such forces to shore based aircraft and coast defences, and the risk of interception.
