All the recent interest in the Russian Kalibr forgets the West's much longer history of hitting insurgents and conventional armies with Tomahawk cruise missiles. Not only missiles but ground attack aircraft like the A-10 Warthog (below).
US Navy warships USS Philippine Sea and USS Arleigh Burke launch Tomahawk missiles on ISIS targets in Syria in 2014. USS Philippine Sea is a Flight II Ticonderoga-class guided missile cruiser and USS Arleigh Burke is the lead ship of the Arleigh Burke-class guided missile destroyers.
The Tomahawk is not alone. There is also the UK-European Storm Shadow, US AGM-86 and more advanced hypersonic missiles in the works.
