So what we have been told from briefing so far:
1. Official bill is $37.5 billion (so far). Far lower than the $110 bil quoted elsewhere (which mirrors the analysis by RUSI about US using lower cost strike packages). But this is still an increase of $8bn compared to the last public estimate. The Pentagon will need a further supplement of $67bn totally
104 billion.
2. Kuh-e Kolah Qazi (Pickaxe) has now been mentioned by POTUS and in several briefs on media by opinionators close to the current admin.
3. On casualties: 18 reported - over 4-month period.
4. This video shared by CENTCOM shows that DDG87 is operating in the region and was replenished at sea (signaling a likely longer deployment in the theatre).
5. Iran will likely see any strike on nuclear facilities an expansion of the war.
6. We can observe an uptick in US Aerial activity in the CENTCOM AOR:

Boeing E-3 Sentry 1x#AE11E7 79-0001 -
Unknown C/S Boeing KC-135 Stratotanker 8x#AE9358 57-1439

7. The incoming UK Prime minster has authorized UK bases for operations against Iran:
^^^
This signals an expansion of the war and a return of bombers...
8. In the most alarming development - increased activity has been seen at Diago Garcia since the UK PM authorised use of UK soverign bases for Defensive operations against IRAN:

Sat Image captured July 20th - 1800 Z
USNS Arctic (T-AOE 8) & Arleigh Burke (likely) alongside
USNS Pililaau (T-AKR 304) in lagoon
8x Fighters, 2x Tankers, 1x P-8 on the south ramp

Conclusion: Safe bet B2's likely could be utilized, however this could be a bluff as we saw during the last strategic strikes on Iran.
