The electrodynamic, electromagnetic and electrohydropulsive accelerating systems of objects are considered. The electrodynamic accelerators of electroconducting bodies are described. Their principle of action is based on the interaction of pulse magnetic field with currents induced in the accelerated body. To increase the pulse magnetic field we use the principle of electromagnetic cumulation of the initial magnetic field created by a superconducting coil. We give the concept of an electric acceleration of large objects having a weight of about 1000 kg till the speeds which are approaching to the space speeds. It is based on the combination of the conduction and induction principles of accel
