From Inside Defense:

Air Force pegs LRSO development at $4.5 billion, dramatically lower than previous estimate

The Air Force has revealed the development cost of the Long Range Standoff Weapon to be $4.5 billion, nearly half the tab for the next-generation nuclear cruise missile the service tallied two years ago, according to service budget documents.

It should have been lower all along. They are reinventing the wheel. We already had a "stealth" ALCM that was scrapped - after being deployed - for a vintage ALCM that was developed when Led Zeppelin was touring. It normally costs less to engineer a copy of something then to invent that thing the first time around. It will probably be a carbon copy clone as there are only just so many ways to engineer a turbofan powered missile with folding fins and mates with a rotary launcher.

I can think of at least four very different ways: Tomahawk, AGM-86, JASSM, and AGM-129.  The new missile will likely look like none of them (though a stretched JASSM could probably be had for fairly cheap and soon).

This would make the missile different than those mentioned:

Yeah, we've been seeing that headline for about 30 years now.

It is very possible that the drop in price is due to the USAF switching to a stretched JASSM variant.

As for supersonics, the US will have to be content with developing all the technology and watching other countries implement the design.

I'd rather have supersonic and hypersonic efforts focus on developing conventional, tactical systems first..that probably has far more chance of securing investments..If the LRSO gets expensive it becomes an even riper target for cancellation by future administrations.

In theory yes, but in practice we will see. I was very intrigued by the possible use of the Mach 3 turbojet for a Mach 2 reusable unmanned reconaissance aircraft.

Mach 2 or 3 is not advantage compare to hypersonic ones.
(Easily targeted by IR sensor but not agile like hypersonic)

Two category weapons are needed

- Extremely stealth but slow (not detected by IR/Radar/Multi-spectral sensor)

- Highly fast (easily detected by enemy sensors, but do not give enough response time to enemy)

Yet when talking about the near future would developing and fielding a supersonic cruise missile or AShM offer a useful stepping-stone to develop and field hypersonic weapons?

Russia, China, India, Japan, and Taiwan all have supersonic AShMs so there must be something there.

Or maybe something like JSOW-ER with a supersonic sprint stage; basically an LO Threat-D.

It sounds more reasonable

Boeing contracted to integrate LRSO cruise missile with the B-52H bomber


Quote
The US Air Force (USAF) Nuclear Weapons Center has awarded Boeing a USD250 million contract to integrate the Long Range Stand-Off (LRSO) cruise missile weapon system with the B-52H large-payload multirole strategic bomber aircraft.

Under the provisions of the contract, Boeing will undertake aircraft and missile carriage equipment development and modification, and full integration and testing of the LRSO for the USAF fleet of B-52H platforms. The programme is expected to be completed by 31 December 2024.

The Air Force Material Command issued a pre-solicitation notification on 10 April 2018, indicating that it intended to award the aircraft original equipment manufacturer (Boeing) up to USD250 million to integrate the LRSO weapon on the USAF's fleet of 76 B-52H bombers between 1 January 2019 and 31 December 2023 (with provision for an additional year if needed).

However, while integration work is now set to begin, the LRSO is still a developmental capability and will not be fielded until the 2030 timeframe.

In August 2017 USAF awarded two separate contracts - each with an estimated, but unconfirmed, value of about USD900 million - to Lockheed Martin and Raytheon for work on the LRSO missile. Both contracts run until 2022, following which the air force will select one concept solution to advance its development under an Engineering, Manufacturing, and Development phase contract.

Intended to penetrate and survive integrated air-defence systems and prosecute strategic targets in support of the Air Force's global attack capability and strategic deterrence core function, the LRSO is a developmental, nuclear-capable cruise missile concept that is being proposed as a significantly enhanced replacement for the currently fielded AGM-86 Air-Launched Cruise Missile (ALCM). Both conventional and nuclear variants of the LRSO weapon are required to reach initial operational capability before the retirement of their respective ALCM versions - around 2030.
