Since we haven't got a canon rendition of this ship so far, I decided to create my own based on FractalSponge's design.

My Lancer-class frigate is equipped with fifteen Corellian AG-2G quad-laser cannons and boasts an enclosed hangar bay that extends from port to starboard, housing two TIE boarding crafts. The aforementioned hangar doors are marked by two white LEGO® ingot pieces. On both sides, right next to the hangar doors, my Lancer-class frigate sports double docking tubes marked by the two light bluish grey LEGO® round 1x2 plates with open studs, so that, when needed, larger crafts could dock with the frigate.

N.B. In the slideshow, the last two pictures are taken directly from the instructions. Also, this MOC has already been uploaded to Rebrickable: https://rebrickable.com/mocs/MOC-224760/BrickRemnant/lancer-class-frigate/#details
