Started the day in ZZZ1 flew to ZZZ for fuel and a quick turn no issues in the flight prior about 30 minutes on the ground at ZZZ. We got our fuel and started engines and taxied out for departure. We had 9;000 lbs of fuel onboard departing Runway XXR at ZZZ it was my FO's leg to fly. We advanced power to takeoff thrust I called V1; VR my FO rotated and called positive rate gear up as I put the gear up we got a very strong dirty sock smell. I let down my sunglasses and the entire cockpit was filled with smoke I immediately told Tower we were returning to the airport for smoke in the cockpit. They then gave us right pattern XXR clear to land at this point I took the controls from my FO and conducted the landing myself on Runway XXR about 5 minutes after takeoff. We taxied into the ramp again shut the airplane down cold dark. I then called mission control and our Chief Pilot.
I was the SIC and Pilot Flying on Aircraft X which was scheduled from ZZZ-ZZZ2. The preflight; startup; and taxi were uneventful. We began our takeoff roll on Runway XXR and all indications were normal. However; shortly after rotation; haze like smoke accompanied by a pungent order started to enter the cockpit. I brought it to the attention of the Captain. We both decided that a return back to Runway XXR was warranted. The Captain who was still acting as Pilot Monitoring alerted ATC that we wanted an immediate return back the runway. We entered the traffic pattern and began heading back to Runway XXR. The Captain assumed the Pilot Flying role on the start of the downwind leg. A successful landing was made and we taxied to the FBO under the watchful eye of airport operations.
EMB-135 flight crew reported haze like smoke accompanied by a pungent odor after takeoff. Flight crew executed a return to departure airport.
