Delta-4

The Delta-4, A New Improved rocket based off of the Delta-3, Same command pod, Same first stage, enlarged second stage, more engines
The rocket weighs an approximate 62t and is stood up on a 40t custom pad.
It has 6.1km/s DeltaV and can make you reach, what 6.1km/s DeltaV, can surely fly by Brigo or Luna
The 24.5m high rocket produces 1.77MN Thrust with the three Kerolox engines taken from the Delta-3
The Second stage produces 2.5km/s DeltaV and is what surely will get you to Brigo fly-by and back
Careful about the re entry, it may be wonky
Seperate the cap at like 5km before activating the parachute

Activation Group-1 is for the improved Door/Hatch which opens the other way compared to the Delta-3, Helping with more accessibility.
Activation Group-2 is for the rocket lights, Four at the nose cone and two inside
Activation Group-3 Must not be turned off else the clamp tower won't seperate
Activation Group-4 Is for the liftoff sequence, caution you must not do anything until the rocket engines are past the tower
Activation Group-5 is pad lights, self explanatory.
