I do not thionk so.
The total refits planned for the Type 23, to keep them VERY relevant until the next generation of FFGs, include their mid-lie and other refits. All of them include the following:
The mid-life refit for all of them included the refurbishment of the mess decks and drive train, the ships being fitted with a transom flap which can add up to 1 knot to the top speed and reduce fuel consumption by 13%, Intersleek anti-fouling paint which added 2 knots to the top speed of Ark Royal. Although the top speed of the Duke class is quoted as 28 knots, an official Navy photo suggests that Lancaster was capable of 32 knots even before her mid-life refit. Finally, the Sea Wolf Mid Life Update (SWMLU) improves the sensors and guidance of the missiles, point defences are further improved with new remotely operated 30mm guns, and Mod 1 of the Mk8 main gun, with an all-electric loading system and a smaller radar cross-section. The communications and command systems are also upgraded.
A further refit, with HMS Argyll being the first to receive it is the Life Extension (LIFEX) Upkeep. Among the upgrades will be the replacement of the Sea Wolf missiles with the new Sea Ceptor anti-air defence missiles.
CAMM(M), the maritime variant of the Common Anti-air Modular Missile, is intended to replace the Sea Wolf missile currently equipped on the Type 23 frigates starting from 2016. CAMM(M) has a longer range of 1–25+ km compared to the 1–10 km offered by the Sea Wolf missile. Like Sea Wolf, CAMM(M) will be VLS launched; however due to its design, CAMM(M) can be packed much more tightly into the VLS, with up to four CAMM(M) fitting into the space occupied by one Sea Wolf missile. CAMM(M) is known as Sea Ceptor in Royal Navy service.
Sonar 2087 is described by its manufacturer as "a towed-array system that enables Type 23 frigates to hunt the latest submarines at considerable distances and locate them beyond the range at which they can launch an attack. Sonar 2087 was fitted to eight Type 23 frigates in mid-life refits between 2004 and 2012; the five oldest Type 23 frigates, HMS Montrose, Monmouth, Iron Duke, Lancaster and Argyll are not scheduled to receive Sonar 2087.
The Type 23's medium-range radar will be replaced by Type 997 Artisan 3D radar. It is a medium-range radar designed to be extremely modular and highly configurable to provide a cost-effective high-performance radar, capable of operating effectively in littoral zones and improving air-defence, anti-surface (anti-ship) and air traffic management capabilities of the Type 23 frigates. Protection measures are also added to maintain detection ranges even when attacked by complex jammers. HMS Iron Duke was the first Type 23 frigate to have received the Type 997 Artisan 3D radar during her refit in 2012–13. It will be fitted to all T23's as well as the assault platforms (LPD) - HMS Albion & HMS Bulwark, the Helicopter Platform (LPH) - HMS Ocean and the two future QE aircraft carriers.
HMS Iron Duke received her new Type 997 Artisan 3D radar in 2013. It is claimed the radar is 5 times more capable than the Type 996 radar it replaces.
These are all the upgrades planned...and I have not read anywhere where the hanger has been enlarged to hold two EH101, or two helicopters of any size.
If you have such documentation, please post it. That would be GREAT enhancement, but I just do not believe anything like that is planned.
Now, the new Type 26 FFGs do plan to have a two helo hanger...so it is coming.
