All around the Fairmile D (697) has same survivability as the other Farimiles. The boat is protected with thin wooden structure and all HE-shells from 40mm to upwards will wipe out the (697) with ease. If you see even a small burst of shells heading to your way, you know the bottom awaits at that point.

Crew size of 30 doesn't help much either as most of them tend to get wiped from the first hits to the boats wooden structure.

Mobility

Speedforward / back

AB75 / 29 km/h

RB54 / 21 km/h

Mobility is comparable to other Fairmiles. For such a streamlined build the Fairmile D (697) is rather slow and tends to be the last on the cap if compared to other similar boats such as the S-boats or PTs.

Like the other Fairmiles, the (697) is somewhat responsive when switching between reverse and forward. There is a delay like with all boats, so getting accustomed to it is recommended. Long build of the boat and sluggishness affects the turning with unfavorable results and it is recommended to not to end up in tight or narrow spaces with (697).

As the Fairmile D (697) sits at rank V, it's RP cost for most of the modules is between 9000 to 16 000 research points.

RP boosters, premium account or talisman wont make spading the vehicle any easier as gaining any points in match with (697) is really hard to due to the boats awful survivability and subpar armament.

Armament

Primary armament

2 х Turret57 mm 6pdr 7cwt QF Mk IIA mounting

Ammunition140 rounds

Vertical guidance-10° / 12°

The Fairmile D (697) is armed with two 6pdr 7cwt QF Mk IIA (57mm) guns. One on the front and one on the rear. These guns pose a mediocre fire rate with mediocre shell velocity and are far inferior to 40mm Bofors for example. 57mm guns are only capable of firing HE so dealing with armored targets is out of it's league, but can reliably hit larger vessels up to a 3,5 kilometres away.

Focus on lightly armored and small wooden vessels with these guns.

Secondary armament

Turret2 x 20 mm/70 Oerlikon Mark V autocannon

Ammunition3600 rounds

Belt capacity60 rounds

Fire rate450 shots/min

Positioned awkwardly in middle of the boat, the dual 20mm Oerlikon is made to fend off small boats which might get too close for the 57mm guns to be effective. Although this requires some maneuvering and thinking your positioning.

Works also as AA gun when the AI wants to hit stuff.

Anti-aircraft armament

2 х Turret2 x 12.7 mm Vickers Mk.V machine gun

Ammunition4000 rounds

Belt capacity200 rounds

Fire rate600 shots/min

2 х Turret2 x 7.7 mm Vickers GO No.5 machine gun

Ammunition4000 rounds

Belt capacity100 rounds

Fire rate949 shots/min

Marginally bad 7,7mm Vickers AA guns have terrible horizontal traverse, so you can forget them as an anti-aircraft guns and also the damage dealt to enemy ships with them is quite minimal.

12,7mm Vickers Mk.V heavy machine guns are excellent weapons for anti-aircraft purpose for planes that are in close proximity, but keep in mind that if the plane is already close, it means you are probably dead in few seconds. Fire rate and damage is decent enough to deal with smaller non-armored boats with lower battle rating. Boats such as LS-3s and Pr.123s are still common sight at 3.3, so taking control of your AA weaponry is recommended in naval CQB.

Additional armament

Setup 14 x 450 mm Mk XV torpedo

Setup 22 x Mk.VII depth charge

Setup 34 x 450 mm Mk XV torpedo

2 x Mk.VII depth charge

Like some of the Fairmiles, the (697) is armed with the common British Four 18" Mark XV torpedos. These torpedos have slow speed of 54 km/h and range of only 5km with the torpedo mode unlocked.

Mk.VII depth charge is a depth charge. You'll might get a kill with them in one game out of hundred if someone is foolish enough to sail too close of you, but due to the survivability of (697), sailing close to the enemy and using the depth charges with purpose is not recommended.

Usage in battles

Both in AB and RB: try to find a cover or a small island. Use your reverse and forward speed to peek. Unload a burst of 57mm HE-shells from range and reverse back to cover. Keep your eyes open for possible targets and avoid heavily armored Russian patrol boats like the MBKs at all cost. It might feel "lowish", but look for weak or half-dead opponents as they are the only prey you can feast upon with the (697)s underwhelming armament.

If taking cover is not possible in the map: stay on the move and try to avoid fire and enemies as the (697) tends to lose against everything due to it's awful survivability. Try to hit enemies on the move with the 57mm guns. Over all avoid sharp turns and combat against multiple enemies in the same time.

Only engage in combat with Fairmile D (697) when you know that you have sure shot, upper hand or you are facing a weaker opponent.

Pros and cons

Pros:

• 12,7mm Vickers are decent against planes and smaller boats.

Cons:

• Wooden structure and no reliable armor means that your survivability in all sorts of engagements is abysmal.
• Armament is subpar when compared to other Fairmiles armed with 40mm Bofors.
• QF 57mm are capable of firing only HE and can't deal with boats with armor.
• Unfavorably high battle rating of 3.3 will ensure that you will face far more superior enemy 3.3 boats and even 4.3 MTBs.
• Fairmile D (697) is rank V, so the RP cost for modifications reach up to 16 000.

• HE large as 105mm or bigger will one shot Fairmile D (697).

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
