well, then each bullet shall have grid position coordinates px,py

The enemy ship has, as well, px,py Grid - coordinates.

So when you save the coordinates for each bullet, you check if bullets px/py coordinate are near ship px,py , something like pseudo code:

Code:

if abs(bulletPX(x)-EShip_px(x))<=2 and Abs(BulletPY(y)-EShip_Py(x))<=2 then 
check for colision
endif

you should see what works better <=2 or <=1 , depending on the grid size.
