[14] The band entered the studio in March 2017 to begin recording the album, recruiting Allom and Sneap to produce it,[15] which concluded in June 2017.

[18] Drummer Scott Travis says that it was "a little bit of both" of a conscious effort to revisit some of the band's musical past organically and naturally, expressing uncertainty in terms of the writings of the guitar riffs.

"[22] Halford said that the band's desire to create the sound of Firepower was to "re-invent some of the classic moments of Priest, which we could trace to the length and breadth of our roots if you think about it with albums like Sad Wings of Destiny, Screaming For Vengeance, Painkiller, British Steel, Sin After Sin, Killing Machine... it just goes on and on (laughs), but internally we knew what that meant so that was the focus".

[23] He describes the album being "an incredible moment, not just for Priest, but for heavy metal", and that its success "shows you don't have much control over the music.

[25] Faulkner described the songwriting process as "free and really relaxed",[26] and that the writing and recording ideas from Redeemer of Souls remained the same, but was slightly different in terms of his guitar performance.

[29] When recording the album, Faulkner used a white Gibson Les Paul that he had used on prior Judas Priest tours for distorted rhythm parts.

Glenn Tipton recorded the album primarily his signature ESP Viper and his old custom Hamer models, as well as a variety of Stratocasters.

[36] He also said that the band did not listen to their classic albums for inspiration during production, "but we certainly thought about what was at the core of all those records, at the metal heart of Priest.

William Nesbitt of PopMatters wrote, "Firepower welcomes fans of previous Priest records, but it also sounds modern.

"[48] Rich Davenport of Record Collector noted, "'Flamethrower' is a weaker moment, somewhat generic in parts, but the overall quality of writing and performance stays high, from Rob Halford's commanding range and presence to the agile Tipton/ Faulkner guitar team's riffing and lead work, the whole band sounding like they've still got something to prove.

"[49] Josh Gray of Clash stated, "...as far as I can tell, Judas Priest just woke up one morning and suddenly remembered how to be the greatest heavy metal band on the planet again.

Though it is far too early to start talking about this as one of their finest records, I have no doubt that Firepower could slip through a wormhole in time to stand in the mighty presence of British Steel and Screaming For Vengeance and feel no shame.

[43] Thom Jurek of AllMusic added "Closing in on their 50th anniversary, Judas Priest still possess the musical rigor, showmanship, and force that make other bands bow down.
