The general thrust equation is then given by: F = (m dot * V)e - (m dot * V)0 + (pe - p0) * Ae. Normally, the magnitude of the pressure-area term is small relative to the m dot-V terms.

Fusion's main advantage is its very high specific impulse, while its main disadvantage is the (likely) large mass of the reactor. A fusion rocket may produce less radiation than a fission rocket, reducing the shielding mass needed.
