Tomahawk | Cruise Missile, History, Uses & Capabilities
Tomahawk, American-made low-flying strategic guided missile that may be launched from naval ships or submarines to strike targets on land. It flies at low altitudes to strike fixed targets, such as communication and air-defense sites, in high-risk environments where manned aircraft may bewww.britannica.com

The Tomahawk is a long-range, unmanned weapon with an accuracy of about 5 metres (16 feet). The 5.6-metre- (18.4-foot-) long missile has a range of up to approximately 2,400 km (about 1,500 miles) and can travel as fast as 885 km (550 miles) per hour.

This is a flight test version of the Tomahawk, a U.S. Navy long-range, subsonic cruise missile capable of being launched from surface ships and submarines. It flew in four tests from 1976-1978.airandspace.si.edu
Tomahawk | Missile Threat
The Tomahawk is an intermediate-range, subsonic cruise missile that is launched from U.S. Navy ships and submarines. It provides a long-range, deep strike capability. The Tomahawk can carry either conventional or nuclear payloads, though policy decisions have phased out their nuclear role...missilethreat.csis.org
Yes there are various versions of it:
Operational
rangeBlock II TLAM-N – 1,350 nmi (1,550 mi; 2,500 km)
Block III TLAM-C, Block IV TLAM-E – 900 nmi (1,000 mi; 1,700 km)
Block III TLAM-D – 700 nmi (810 mi; 1,300 km)[8]
Block IV - 864nmi, 1000+ miles, 1600+ km
Block Vb - 900+nmi, 1035+ miles, 1666+ km (exact range is classified)[9]
RGM/UGM-109B TASM - 250 miles, 460 km[10]
But in essence it is a 2400 or 2500 km range cruise missile as far as its max range goes. It‘s length varies from 5.56 to 6.25 metres. That means the amount of ammo and fuel it carries will vary and in turn it’s range will be affected. Moreover, US and its other users UK and Australia, will not want real figures to be open to public and to their potential adversaries. And as part of public we have to take the given maximum range as a valid effective range.
Also, since we are discussing the reason of using a turbofan here, it is irrelevant if the range is 1600 or 2400 km. There are versions of it with turbojets and even a ramjet 3mach speed version is being worked on. Some versions have no more than 460km range.

Block II TLAM-N....Means nuclear warhead version and those retired 10 years ago
5.56 length of missile...and 6.25 with booster
