I did.
Here is a different and more detailed version.
1. Cap's shield has never endured the might of something twice Superman's might.
Thus it's durability is lower than twice Superman's might by default.
2. Superman, using all of his might couldn't even scratch the missiles.
3. At less than half power, the OB vaporized the missiles proving that at full power the OB is more than 5 times more power than Superman's might. Note: vaporizing something takes more than a thousand times more power than just damaging something.
Conclusion:
It follows that Cap's shield is weaker than those missiles in durability. But I'm giving Cap's shield the benefit of the doubt since it is well known. So those missiles are close to the durability to Cap's shield.
