Similar to the Soma, the Phaedra has a short wind-up time before it reaches its full fire rate. Though the Arsenal lists a fire rate of 12.5, this is the fire rate before spool-up. Once fully spooled, the Phaedra has a maximum fire rate of 25 rounds per second, 100% above its Arsenal value. The fire rate listed in this page is the average of its initial fire rate and its maximum fire rate.
Though it's described as "the Soma's big-sister", it's more-so due to the aesthetic design, and not the actual stats of the weapon.

Phaedra is a character in Greek Mythology best known for her role in Euripides' play, Hippolytus. Phaedra's name derives from the Greek word φαιδρός (phaidros), which meant "bright".
It appears that the Phaedra's UI icon is missing its barrel-like magazine. This can also be seen on the Karak Wraith.
‘ATMOSPHERE’ ARCH-GUN WEAPONS
It’s time we equipped some serious floor firepower! All Arch-Guns can be used on the ground - or as we like to call it ‘Atmosphere’ - with the use of a ‘Gravimag’. Gravimag is obtained from Clan Research, or as a one-time reward from the Orb Heist Phase 3 Bounty, and can be installed on any Arch-Gun (with an Orokin Catalyst installed) via the Upgrade Arsenal - similar to installing a Catalyst.
Comparable to the Archwing and K-Drive Launchers, a respective Gear item known as the Archweapon Deployer is required to activate your Atmosphere Arch-Gun. The Archweapon Deployer can be obtained by completing the Orb Heist Phase 3 Bounty.
Atmosphere Arch-Gun General Changes:
Atmosphere Arch-Guns consume Ammo as opposed to unlimited Ammo/Battery in Archwing. Specifically new Heavy Ammo Drops which can be found from Corpus enemies in Orb Heist missions. Heavy Ammo Drops also reset the 10 minute cool-down when picked up, or replenish Ammo if needed.
Atmosphere Arch-Gun can be summoned in normal missions with the Archweapon Deployer, but once Ammo has been depleted there is a 10 minute cool-down until you can summon again. The intent here is to allow you moments of beefy damage output, and not become just another Primary/Secondary weapon.
All stat changes are for Atmosphere Arch-Gun mode, Mastery Rank changes are global:
