For the seventh mission, Metal Hawk will start out directly over the two rocks at the top of the area; once the area's theme, which is identical to that of B-6, starts to be heard from that Yamaha YM-2151, push that lever up to descend to 150 metres while that arrow appears in the centre of the screen and points you towards the first oil rig (surrounded by seven more rocks) in the centre of the area, as the Japanese speech sample is heard from the C140. It has four Type 4 Cannons firing anti-aircraft missiles at you from their positions upon it (which you can drop one of your own missiles on for 10 points apiece), along with four oil tanks and one medium-sized building (which you can also drop a missile on, for 5 and 20 points respectively) - and once you drop a missile on each of these, to kill or destroy them, the rig will launch two Red Heli and two Green Heli into the air (they will fly towards you once they have reached your altitude, and can be shot for 10 points apiece). Once you have fired a shot at each of these to kill them, that arrow will reappear in the centre of the screen and point you towards that second oil rig (surrounded by four more rocks), in the bottom-right corner of the area, as the Japanese speech sample is again heard from the C140; there are four more Type 4 Cannons firing anti-aircraft missiles at you from their positions on it, along with four more oil tanks and a second medium-sized building. Once you have dropped a missile on each of them to kill/destroy them, the rig will launch two more Red Heli and two more Green Heli into the air - and once you have fired a shot at each of them to kill them, the arrow will again reappear in the centre of the screen to point you towards the third oil rig at the bottom of the area surrounded by one last rock as the Japanese speech sample is once again heard from the C140. It has four more Type 4 Cannons that are firing anti-aircraft missiles up at you from their positions on it, along with four more oil tanks and a third medium-sized building; once you have dropped a missile on each of them to kill or destroy them, the rig will launch two more Red Heli and two more Green Heli into the air. Once you have fired a shot at each of these, to kill them, the arrow will once again reappear in the centre of the screen then point you onto three boats and two Mini Battleships sailing through the water on the left side of the area as the Japanese speech sample is yet again heard from the C140 - the boats both have two Type 1 Cannons mounted on them which will be firing more anti-aircraft missiles up at you, like the Mini Battleships are doing from their behinds. Once you have dropped one of your own missiles on each of them to kill them for 10 points apiece start dropping missiles on the various parts of the boats themselves to destroy them for 10-20 points apiece (if you manage to destroy them completely, they are worth 100 extra points); once you have reached 650 points, the "stage clear" theme will be heard from the Yamaha YM-2151 for a seventh time, as Metal Hawk flies back up to its highest altitude of 400 metres and off the top of the screen. You will then get 10 bonus points for every second you have remaining - and if you had not attained the military ranking of Marshal by the time you had cleared the previous area, you probably will have by now. Metal Hawk will now proceed onto Area G-11: The Last Target; as its name suggests, it's the last area of the game.
