Aircraft
Normal preflight start and taxi. No noted issues with the aircraft prior to takeoff. I was accomplishing the takeoff as the F/O. We were cleared for takeoff. Takeoff was normal until after the gear was up and we noticed a steady loud noise. Shortly after; we noticed a Master Caution light. The aircraft was not pressurizing and a Forward Cargo door light was illuminated. The Captain coordinated with Tower to return to the field. I continued to fly the aircraft for the approach and landing. No other issues were noted.
