Excalibur Galatine

is the shining sword that Gawain possesses. It is the sister-sword of Excalibur, also originally owned by the Lady of the Lake, but it is not as well known as a holy sword and rarely mentioned due to having its legend hidden in the shadow of King Arthur's holy sword. While Excalibur collects the lights from the planet, Sir Gawain's holy sword is said to represent the rays of heat from the sun with a Pseudo-Sun contained in the hilt.
 Arthur has the providence of the night from the pedigree of the goddess of the moon, Alto and Artemis, and Gawain is the knight who receives the blessing of the sun. It is similar to its owner in that it shows its greatest power at noon, making visible the unsurpassed sharpness of the edge that sliced cleanly through both the shield and chainmail of the enemy Saracen soldier, Priamus.
Differing from Excalibur's centralized slash of light that destroys castles, Galatine brings forth a broad wave, radiation-type attack that completely annihilates an enemy army. Its sun characteristic is reflected in its activation like rays of heat from the sun. Gawain tosses the sword into the air where the pseudo sun inside creates a miniature sun before landing back in his grasp. While the sun floats overhead, he generates a large magic circle with a sun symbol in the center under him as he draws the sword behind his back. With a motion like drawing a sword, the pseudo sun, and the energy put into it, the attack extends as far as it is possible to visualize the blade of the sword, around thirteen kilometers "or so", like its prototype, Caladbolg. He unleashes a horizontal slash of flame that pierces through the enemy and erupts into a giant ball of fire that engulfs them. 
 However, it has also been shown possible to employ a Vertical Slash and Thrusting Variation, indicating it is not limited to its standard horizontal, wave-like attack.Fate/EXTRA Last Encore - Episode 11: "Excalibur Galatine" Even if the blade itself were to be physically broken, Gawain can still fire his Noble Phantasm, stating that his blade "answers to the will of my lord!"Fate/EXTRA Last Encore - episode 13: "Olympia Plaudere"
