The F-41 Exoatmospheric Multirole Strike Fighter, also known as the Broadsword, is a versatile and well armed A/X strike fighter typically used to engage space craft of equal or superior weapon capabilities and evasive flight capabilities in low to zero gravity conditions. As its kind has few equals within the UNSC's arsenal, the Broadsword was designed to address the incredible firepower displayed by the fighters of the Covenant such as the Seraph and Space Banshee.
This vehicle can be seen in the E3 2012 live action trailer "Commissioning". Many of them were parked on platforms during the speech, and a few can be seen flying when the fleet was heading towards Requiem.
The Broadsword may be the successor of the Sabre as they seem to have similar roles and design.
The Broadsword makes an appearance in the second-half of Spartan Ops Season One, as seen in the trailer.
Like the Longsword, the Broadsword appears to be able to perform within atmosphere, as seen in Infinity, Reclaimer, and a Spartan Ops episode.
The throttle appears to be located on the right side of the cockpit. This is unusual since modern fighters, like the F-15 Eagle, and many other fighters, have it on their left.
Oddly it is present during the Battle of Tribute. It should not be present as the F-41 was not yet in production.
Although this could be that the Broadsword could have been in its experimental stage and they were stationed at Tribute.
