Varda to buy 4th Photon. Article didn't say who was launching it.

With the Neutron barge landing discussions briefly drawing some attention back to RL, I did a quick Electron launch check on Wikipedia.Wikipedia says 3 launches so far in 2022, and we’re almost half way through the calendar year? What gives? Hardly promising stuff.
If it is capstone delay, they can use other pad to launch their next customer's payload.

Or… maybe it isn’t a customer delay. (Or if it is, I’m not sure that helps, because that suggest they don’t have enough customers)They will soon have 3 pads operational, and their launch cadence is not scaling to match. Their launch rate has not yet come close to needing a 2nd pad.As it looks right now, the other two pads were a waste of funding that desperately should have gone to accelerating Electron manufacturing or Neutron development.[EDIT - Fixed quote tags]
With multiple pads now operational, what’s the tightest bottleneck to launch cadence now?
Most of the time it is customer readiness. Rockets roll off the production line roughly every 18 working days right now, but we can only fly when the satellite is ready to.

Demand != readyness. Even for smallsats, there are lead-times between choosing a launch provider and purchasing a launch, and the satellite actually making its way to the launch site.

Rocketlab is presumably in contract negotiations with many customers at once, with the negotiations in different stages. So it is no explanation for the low launch rate.

Rocketlab is presumably in contract negotiations with many customers at once, with the negotiations in different stages. So it is no explanation for the low launch rate.There's also the delta between a given customer making the decision that they want to launch their payload on a cubesat on Electron (or hosted payload on Photon) rather than another option (e.g. rideshare cubesat, shared smallsat, ISS hosted payload, ISS deployed cubesat or smallsat, etc), and that customer actually having developed, built, and tested that payload/vehicle and being ready to launch.

Doesn't matter how long N is, it imposes a delay but after N months they should be launching at whatever their contract-signing cadence is.And yes, obviously N isn't the same for all contracts, but that should mean they sometimes launch multiple times a month in addition to sometimes skipping months. If they only skip months, that isn't consistent with their contract-signing cadence being one a month.
We’ve completed the 2,000th successful hot fire of our Rutherford engines! 260 of these 3D-printed, electric pump fed Rutherford engines have now been launched to space, playing a pivotal role in enabling frequent and reliable access to space for smallsats.
Responsive Satellites:Whether it’s one or one hundred satellites, Rocket Lab can design, manufacture, launch and operate configurable satellites tailored to each customers’ mission. To support responsive replenishment of orbital assets, these satellites can be built and kept in a state of launch readiness, awaiting integration with the customer payload and launched on demand, either on Electron or alternative launch vehicles. Rocket Lab’s deep space systems heritage spans complete satellites through to subsystems and individual components, including space solar power, structures, radios, separation systems, propulsion, flight software, star trackers, and reaction wheels. More than 1,700 spacecraft on orbit feature Rocket Lab technology, including Photon spacecraft designed, built, launched and operated by Rocket Lab. By producing these vital subsystems in-house, we have a high degree of supply chain certainty and rapid production timelines.
https://investors.rocketlabusa.com/news/news-details/2022/Rocket-Lab-Introduces-Responsive-Space-Program/default.aspxRL announce responsible launch program.Given the bottleneck is customer payload readiness, it's not surprising they may have some already build rocket in hand that can be used in short noticed.But however, who is going to use this other than gov?If you only have very few satellites, it's unlikely you can build a satellite this quick, or have a spare satellite in ready for launch.If you are a large constellation that launch frequently (like Planet lab), you can just add whatever you need to next batch to be launched. And you may also have in orbit spares.However, the announcement also has this sectionQuoteResponsive Satellites:Whether it’s one or one hundred satellites, Rocket Lab can design, manufacture, launch and operate configurable satellites tailored to each customers’ mission.

But unless the constellation is build on RL bus, I think you can not plug in your payload and launch tomorrow.
