F-15 Eagle: History, Performance & Discussion

that changes quite a bit, even in the worst case scenario it would hit like slightly stronger hellfire.

Well. If gaijin will give it 170+ warhead preset - yes.

Isn’t it AFX-757 for the SDB II?

No, I don’t think. It’s for GBU-39 series.

There is no reason to use AFX-757 when you make “anti-tank” bomb

The Small Diameter Bomb (SDB) II, also known as the Guided Bomb Unit (GBU) 53/B, is the United States (US) Air Force’s newest standoff weapon to use miniature munition technology in combination with an all-weather guidance seeker designed to support a land offensive. The SDB II uses the US Air Force’s new explosive material, Air Force Explosive 757 (AFX-757), in combination with target recognition software giving aircraft the capability to strike moving targets in all-weather conditions with up to four times more weapons per aircraft.”

Hm, interesting…

Use the AFX-757 when you have a HEAT warhead in general…

Well it’s rated as an insensitive explosive and has an Re Factor ~1.85 (vs TNT, 1.39 vs Comp. B), so it’s not a bad choice, Also it technically counts as thermobaric / FAE explosive.

Well, Let’s see what Gaijin will add.

For a multipurpose munition having a thermobaric component seems like a great idea

nope programable HEAT or HE

All in effect it means is that the mass balance of the reactants is deliberately skewed within the explosive mixture to contain more reducing agents(reaction fuel) than oxidizer, and so it uses Atmospheric oxygen as part of the reaction chain to facilitate that excess fuel.

This basically makes it far more fuel efficient by mass than other chemicals since for a fixed total weight, you get a lot more Energy & heat out. The tradeoffs are effectively twofold, where care needs to be taken to disperse the fuel and ensure that it evenly reacts since it may otherwise dud or, not completely combust since the net reaction isn’t stoichiometrically balanced by design.

It’s a multi-functional warhead (so SAP-HE, HE-F and HEAT-F are all likely possible depending on target), also with a Ram air turbine to generate electrical power it should be able to glide indefinitely as long as it has altitude, at the cost of higher drag.

If the C got EPAWSS because of testing, would it also get the increased countermeasures count?

But why would the fuse need power? Might have an Airburst functionality, neat.

But why you need ATA for airburst?

It was specifically mentioned that the fuse was failing due to needing power as the voltage needed is simply generated on impact via a piezoelectric Quartz crystal plate being crushed for an impact or delay fuse.

And a similar issue was caused with the DSU-33A/B & DSU-33B/B for the JDAM for the F-14B &-14D, not being able to take full advantage of their range, which was fixed with the DSU-33C/B.

Both fuses may be employed with the DSU-33A/B proximity sensor to provide an airburst capability. Currently, the specified battery life for the DSU-33A/B proximity sensor is 60 seconds after release However, demonstrated battery life is greater than 90 seconds and the technical orders are being updated to reflect the new time. The 90 second battery life is a limitation to JDAM employment, and must be considered during mission planning.

Interesting… So yes, it have HOB.
