Earlier this week I took the liberty to get some more intel on that defense platform them Baffin zoners build on the jumphole.
The station itself, also known as Malaclypse station is approximatly 2 kilometers away from the jumphole.
The "platforms of death" are build on two sides of the jumphole in rows of three. Judging on the size and velocity of the rounds they fire I would say they are all fitted with heavy weaponry. Ment to take out or at least cripple capital ships.
While I was in the system I also picked up a transmission, I tracked it and it came from Malaclypse Freeport. Long story short, it seems that if we ask these zoners for access rights, they'll let us pass through their system again.
It might also be interesting to know that our ships are agile enough to get through the barrage of these six platforms if you want to jump to Tau-29... However, if you jump from Tau-29 to Baffin, a certain death awaits you.
