SpaceX successfully recovered every fairing half that flew between May 2021 and June 2022.

In an effort to continue the success of the fairing reuse program, SpaceX is again experimenting with new recovery methods.

By my count, today's @SpaceX #Starlink launch marked the 100th fairing half reuse in only a few short years.

That's pretty huge and I feel like the whole fairing reuse aspect is largely underappreciated by the public.

This actually makes me wonder how much this experience has fed into the Starship Bellyflop maneuver.  The aerodynamics are similar, albeit different in scale and speed.
Following the space program since before Apollo 8.

Departure! Bob is heading out to sea for further testing of SpaceX's new inflatable fairing recovery net system. (The big red sausage on top deck)

This method of lifting fairings from the water was first trialled a few months ago.

Is there anywhere that keeps a running count on fairing reuse the same way they do for boosters?  What fraction of recent uses reused fairings?

Is fairing reuse now too boring to deserve reporting?

I don't know where I saw it, but someone is keeping track of fairings. Nice chart and everything you'd expect for SpaceX hardware tracking...  :D
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

Only 3 missions with mixed used/new halves. I wonder if there's a particular reason they don't like to mix them, or that's just the way it's done.

Has all the r&d costs for the re-use of fairings now been recovered in the savings from reusing fairings?

Speculation:  The new fairings are being flown mainly because a customer wants a new fairing, and no customers are interested in flying with just a half-new fairing.  New fairing halves are still being made, but only slowly, and they're being held back for customers willing to pay extra.

The answer might depend on what all you consider a part of the r&d, and what falls under operational recoveries.

Considering the proposed number of launches, I can see the r&d either as being paid off by the savings, or within six months of doing so.

The cost per fairing half has crept up from $2.5M to $3M.  If the cost per use can come down to $500K per half, hopefully more, it looks to me like that cost of developing this capability has paid itself off.

Beyond simply paying for itself, it's doubtful that SpaceX could produce 60 full sets of fairings in a year to enable the current launch rate.  So like booster reuse, the ability to reuse hardware has enabled capabilities, like Starlink deployment, that would have been very difficult to manage without.

Which makes full reuse of a rocket system very exciting to anticipate.  What benefits and capabilities will be possible when full reuse and rapid flights are possible/routine.
Wildly optimistic prediction, Superheavy recovery on IFT-4 or IFT-5 (Welp a little early on IFT-4, but still have a shot at 5)

@SpaceX faring migration season is surprisingly short as I saw these two flying south a few days ago but they are already on the final leg north returning to their roost. I expect it will soon be faring mating season.

This was the first time flight-proven fairings supported a Falcon Heavy mission, and it was the farthest downrange landing and recovery of fairings to-date at 1,200+ miles nearly a third of the way to Africa!

Fairing reentry on the ViaSat-3 mission was the hottest and fastest we've ever attempted.  The fairings re-entered the atmosphere greater than 15x the speed of sound, creating a large trail of plasma in its wake
