Summary
Aeronautic Subsidy adds a big chunk of money saving for the expensive Ace upgrades. This is most significant for Flying Fortress, which is the most expensive of the trio. It is also useful with Sky Shredder for excellent general popping power for a moderate price, as well as Tsar for dealing with super dense rounds.

Tips

 * If wanting to ace the rounds up to 100 much easier with a Flying Fortress to near-solo them, this MK is very useful for that purpose.
 * Race Events that enable Tsar Bomba benefit from this MK a lot, as it lets Tsar become more affordable so it can wipe out many bloons on screen with ease.

Trivia

 * All discounts from Aeronautic Subsidy cause the Impoppable prices of Tier 5 Ace upgrades to become their old respective Hard prices.
