Oh, you have reached a new level of stupid I see!
How does a ground-launched cruise missile get to speed so that the jet engine can take over propulsion? Do we have big strong Nebraska corn-fed youngsters that can pick it up and throw it like a paper airplane?
Why don't you just shut up?
The only people you are impressing is how you can operate a computer on the internet being as stupid as you are!
Tomahawk cruise missiles are often installed on ship, so obviously can easily be launched from land as well.
A logical way would be for the jet engine to start to run on an electrical, solid fuel, or other means of compression.
The Navey obviously has figured out how to do it.

Each missile is stored and launched from a pressurized canister that protects it during transportation and storage, and also serves as a launch tube.
[43] These canisters were racked in
Armored Box Launchers (ABL), which were installed on the four reactivated
Iowa-class battleships
USS Iowa,
USS New Jersey,
USS Missouri, and
USS Wisconsin. The ABLs were also installed on eight
Spruance-class destroyers, the four
Virginia-class cruisers, and the nuclear cruiser
USS Long Beach. These canisters are also in
vertical launching systems (VLS) in other surface ships, capsule launch systems (CLS) in the later
Los Angeles-class submarine and
Virginia-class submarines, and in submarines'
torpedo tubes. All ABL equipped ships have been decommissioned.
For submarine-launched missiles (called UGM-109s), after being ejected by gas pressure (vertically via the VLS) or by water impulse (horizontally via the torpedo tube), a
solid-fuel booster is ignited to propel the missile and guide it out of the water.
[44]
After achieving flight, the missile's wings are unfolded for lift, the airscoop is exposed and the turbofan engine is employed for
cruise flight. Over water, the Tomahawk uses
inertial guidance or GPS to follow a preset course; once over land, the missile's guidance system is aided by
terrain contour matching (TERCOM). Terminal guidance is provided by the Digital Scene Matching Area Correlation (
DSMAC) system or
GPS, producing a claimed
circular error probable of about 10 meters.
The Tomahawk Weapon System consists of the missile, Theater Mission Planning Center (TMPC)/Afloat Planning System, and either the Tomahawk Weapon Control System (on surface ships) or Combat Control System (for submarines).
