Today I’ll be reviewing the Cobra AEROJET irons.
Falling in the game-improvement category, the AEROJET irons are all about providing effortless speed and launch. Every technology contributes towards maximum face flexion at impact, and a soft polymer fill also helps fine-tune acoustics and feel.
How do the AEROJET irons compare to the previous LTDx model? What are its strengths and weaknesses? Who are they best suited for? Is it worth putting a set in the bag?
Read on to find out what you need to know to make an informed purchase.
What are the reviews like?
The AEROJET irons has been received positively overall, but critics have noted the strong lofts and rather limited stopping power. The irons earned a gold medal on the 2023 Golf Digest Hot List.
What People Like
- attractive design
- outstanding distance
- excellent forgiveness
- feel is very solid and responsive
- more affordable than other brands
What People Don’t Like
- strong lofts with lowish spin
- look is too chunky for some
The PWR-BRIDGE technology takes inspiration from an idea of Leonardo Da Vinci back in the 16th century.
Sitting slightly above the sole, it consists of a 70g floating steel weight suspended in a soft polymer filler meant to enhance sound and feel.
This new design shifts the center of gravity (CG) low and forward, allowing for 10% more face flexion at impact (compared to the LTDx) and hence more ball speed. The effect is most pronounced low on the face and in the toe area, which is a common mis-hit location.
A forged L-Cup PWRSHELL face insert wraps under the AEROJET iron’s leading edge. This variable-thickness insert is 22% larger than the LTDx in its thinnest region.
The end result is more face flexion low on the face, higher launch, and higher ball speeds.
A.I. H.O.T Face
The idea behind H.O.T (“Highly Optimized Topology”) is similar to Callaway’s A.I. Flash Face.
Using machine-learned data from thousands of impact simulations, the thickness of the face is optimized in multiple locations through CNC machining. The result is more efficient spin and increased ball speeds across the face, not just in the sweet spot.
This technology gets its name from the fact that these zones create a topology map consisting of peaks and valleys.
The purchase of Cobra golf equipment like the AEROJET irons immediately makes you eligible to receive free Arccos Smart Sensors and a one-year free trial to the Arccos Caddie app.
Arccos sensors are attached to the clubs in your bag and enable automatic shot tracking, real-time GPS yardage information adjusted for environmental conditions, caddie advice, and post-round strokes gained analytics.
Arccos features can be accessed through a smartphone, smart watch, or Arccos Link device. It is said that Cobra players improve by five strokes on average after their first year using the Arccos Caddie system.
There are many set configurations to choose from, from the 4-iron all the way to the sand wedge. The stock set is 4-PW.
Also available are the:
- AEROJET ONE Length Irons: the lengths are the same at 37.25″ (7-iron), enabling you to keep the same setup and swing throughout the set
- Women’s AEROJET Irons: has light blue accents and offers club lengths, shafts and grips that are tailored to women to maximize their performance
- AEROJET Combo Set: consists of six irons and an AEROJET hybrid for added forgiveness and playability
The stock shafts are the KBS TOUR Lite (steel) and KBS PGI 85, 75, 65 (graphite). The stock grip is the Lamkin Crossline 58R. Custom options are available.
If you’re interested, more information on shafts, grips and other customizations can be found here.

The AEROJET irons undoubtedly pack a lot of distance, but pitting them against the previous generation LTDx, it’s honestly hard to see much of a difference. The differences I did see can be summed up as follows:
- the launch angle is higher by about 2-3 degrees
- spin is maybe just a touch lower by no more than 50 RPMs
- ball speed is about the same
The end result of the above is that the AEROJET irons fly about the same carry distance but roll out less than the LTDx. This improved stopping power is what you want, but it’s certainly less than what you would see out of a typical players iron.
The same technologies that make the AEROJET irons so long also make them very forgiving.
Ball speed retention on mis-hits is outstanding. Even my worst strikes didn’t lose more than 10 yards of distance compared to center strikes.
Dispersions are also excellent. During my tests, all of my shots tended towards my natural shot shape, and it took a really poor swing to miss the green clear.
Even though I didn’t notice much of a difference in forgiveness compared to the LTDx, I still feel like the overall level of forgiveness is right where it should be for a modern GI offering.
Trajectories with the AEROJET irons tend to be medium with no particular flight bias either way. While shots tend to be penetrating and hold up well in the wind, the low spin and strong lofts make for quite a flat trajectory which some will not like.
Stopping power is still good, but I would have liked to see a more controllable ball flight. You can’t expect much when the lofts are identical to the LTDx, but I foresee many golfers with lower swing speeds struggling to get enough carry with the longer irons.
Turf interaction is great; the AEROJET irons cut through the turf nicely. This makes fat shots a much less unpleasant experience than they otherwise would have been.
Workability is surprisingly good. I expected it to be more or less the same as the LTDx, but for reasons that that I still haven’t figured out, it was easier to put curve on my shots during testing.
The AEROJET iron has just as much bag appeal as the LTDx in my opinion, with a cool badge design, chrome finish, and tasteful red and blue accents that add a bit of pop.
The top line is appropriately thick for a game-improvement iron, but unlike the LTDx, it’s chamfered which makes it look slimmer at address.
Aside from that, the iron looks quite bulky — this can inspire a lot of confidence when set up over the ball but will not appeal to everyone. The stronger lofts combined with the relatively wide sole means that you can see some of the cavity sticking out of the back in the longer irons.
The LTDx irons had a relatively small amount of offset considering their forgiveness and the AEROJET carries this forward. The offset is exactly the same through the set, so golfers looking for more offset in their irons should look elsewhere.
The Sound & Feel
The feel of the AEROJET iron at impact is very solid and strong — very similar to the LTDx and reminiscent of a forged club. There is also an element of hotness and a metalwood-like quality to the feel in some respects.
The sound at impact is a medium-pitched “clap” that is slightly muted and subdued.
The main thing with the AEROJET irons is that you really feel like the ball is shooting off the face, and I reckon most mid and high handicappers will appreciate this.
I’m impressed with how well the feel is preserved in mis-hit areas, not just in the horizontal direction (heel/toe) but also in the vertical direction. Vibration are kept to a minimum.
On the flip side, feedback is no more helpful in the AEROJET than it was in the LTDx, so it can be difficult to discern the general area of the strike.
Where To Buy These Irons Online
One place I recommend ordering AEROJET irons which allows complete customization control (configuration, lie, shaft, grip, etc.) is PGA TOUR Superstore. Check out the following links:
- AEROJET irons with steel shafts
- AEROJET ONE Length irons with graphite shafts
- AEROJET ONE Length irons with steel shafts
- AEROJET Combo Set with graphite shafts
Not only does PGATS accommodate custom requests for most new models, but they also offer financing plans, performance guarantees, and club trade-in programs to help you minimize the financial hit and maximize peace of mind.
If you want to save some money, you can find discounts on eBay. Optionally look at what’s available on Global Golf, which is one of the best used golf equipment stores online.
Standing on its own, the Cobra AEROJET is an excellent game-improvement iron, albeit one with strong lofts, lower spin, and less stopping power than many other models. Its main attraction is explosive distance across the face.
When it’s put side-by-side with the previous LTDx model, there just isn’t much of an improvement to speak of. The differences are too marginal, and this shouldn’t really be surprising considering the technologies built into it are largely the same.
If this is your first new set in a while, putting these irons in the bag could be a great idea. But if you own the previous LTDx or even the RADSPEED and are happy with the performance, it’s probably not worth the upgrade yet.
