There most certainly is a review. It’s doing far more obviously than just what I wrote above, but getting more fires from Navy is one aspect I think will actually seriously be looked at.
Up arming the Arafura Class is a contentious subject here on DT, but none the less it's still a subject aired on many other defence publications.
Their size, space and weight will always present a challenge for weapons growth.
None the less.
I'd suggest some modest lightweight systems may be the starting point.
An ATGM such as Spike being introduced for Armys boxer has potential.
Comes in various sizes with a Non line of sight version performing out to 20 plus KM's or the lighter ER11 out to 10 km.
Either will certainly give options beyond the ships 40mm main gun.
Another option is a short range SAM in the Stinger / Mistral Class.
Good for keeping some intriguing helicopters / UAV's some extra distance from your ship.
Navy seems to like the Schiebel S-100 UAV.
This useful aircraft has some weapons scope that should be prioritized.
Will give the vessel a very good long range sensor / hard kill ability
Some passive defence measures should be considered.
The in service Nulka may seem an indulgence on a OPV, but would add some reactionary capability to unwelcome escalation.
Would also add to the Arafura's ability to sail with the majors in a greater range of contingency's.
Much talk of the class acting as a node as a part of the fleet has potential.
The above are not about engaging a major Air / Sea threat, but rather to give some extra options in the Grey zone which I feel will be tested in the years ahead. I agree with Redlands that the OPV's will sail further afield visiting and patrolling the South Pacific and suggest also the equivalent distance to our North and West.
The Arafura Class should perform a more robust role INDEPENDANT of major fleet units.
We want to avoid seconding Destroyer / Frigates from doing constabulary roles.
They should also be able to compliment the Majors in appropriate circumstances.
They do have some space and weight to add to their potential.
