Why or why not? Standard procedures call for gear up very early in the routine, often immediately after power is added. Whether it's absolutely necessary or not depends on the situation, but the procedures assume maximum climb performance is immediately required. They generally set things for maximum power, maximum lift, and minimum parasite drag. The gear is a big drag item. There are some aircraft that put the gear-up operation a bit later in the sequence. The reason is that with some systems the gear in-transit actually generates more drag than the gear down does. It is true that flaps & leading edge slats also generate some drag. But this drag is tolerated since at go-around settings they produce a great deal more additional lift than they do added drag. The net result is a steeper climb angle.
