You need 6 dispensers, few repeaters some redstone, water, some filler material and TNT for 5 dispensers on the back and preferably an orc bomb of any kind in front one. Stronger bombs you have, more effective it gets, I recommend tier 3 fire bomb (the strongest one in survival).

The five back dispensers must all be facing into one spot like it's shown on last screenshot. The repeaters are needed to give enough delay for the last AKA front dispenser to place it's bomb within the second from detonation of original five TNTs.

That way the bomb will fly extremely far instead of dropping after 10 blocks of flight.

Sorry for amount of time I needed to answer.
