Is the first stage recovery controlled or does it just deploy parachutes? The second stage still had ~7500kmh at 115km altitude when they lost it - that strikes me as a large landing zone (I guess that's nowhere near enough for LEO)
The second stage would not have been able to achieve orbital velocity. It looks like the engine shut down almost as soon as the second stage ignited. At the moment of failure the indicated velocity iwas 8,072 kph. Orbit velocity is 28,000 kph - so well short of orbital velocity.SFN are reporting that the 2nd stage appeared to tumble as the engine ignited

Full statement from RocketLab - seems the 1st stage splashed down OK

Well that’s something. Looked like the upper stage engine gimbaling just went hard over after staging.
On Monday, ULA are launching the first Atlas V since last November. They don’t super chill their RP1 kerosene, so they’re loading it up already.
This will launch the Space-Based Infrared System (SBIRS) satellite for the US Space Force. This is a missile launch detection system.
The launch is from Cape Canaveral at 6.35 pm UK time.
It’s in 421 configuration, so the smaller 4 meter wide fairing, 2 solid boosters and 1 upper stage engine.

ULA having another go, but have just gone into an unplanned hold
