Romeo Serials?

[Martin Edwards]

There are very few visual differences between the Seahawk Bravo and Romeo models yet they received different serial prefixes.
The S70B carries N24-xxx and the MH60R carries N48-xxx

Compare this with the Hercules that has had four very different model over 50 years yet retained the A97-xxx serial,
the F-111 two distinct models both A8-xxx
and the Chinook with three models all A15-xxx,
There are many other examples of different aircraft with the same series serial.

Beaufighters had two different A numbers

[Martin Edwards]

True that the Beaufighters had different serials for the imported and locally built examples.
I think that was also to use up the vacant A8- prefix that was going to be used for the Bristol Blenheim.

The other anomaly is that the A19 aircraft were delivered before the A8 aircraft!

So I think that the Beaufighter was more the exception than the rule.
Most of its WWII contemporaries kept a single prefix over sometimes many different models.
