The MBF-P03D Gundam Astray Blue Frame D is a variant of the Gundam Astray Blue Frame Second L/G in the novel Mobile Suit Gundam SEED Destiny Astray B. It is piloted by Gai Murakumo.

Produced in the Ame-no-Mihashira's factory by Gai, the Gundam Astray Blue Frame D is a close combat unit created to battle Dante Gordigiani's MBF-P0X Gundam Astray Noir. Although it is a variant of the Blue Frame Second L and Astray Blue Frame Second G, the Gundam Astray Blue Frame D swaps out most of their parts for parts of the original Blue Frame. Newly designed parts are also fitted in some areas and a striker pack connector has been added to the suit's back so that it can mount the Vouivre Striker, a modified AQM/E-X01 Aile Striker. The suit is armed with 10 blades and gives the impression that it is designed to get close to the enemy using the powerful output from the Vouivre Striker and then engaged in close combat. However, these blades are actually DRAGOONs with unique abilities and most of them can also be used as handheld weaponry. Gai later upgrades the suit with a pair of blade guns that are mounted underneath the arms.
