I bet you didn't know that the United States Navy has, overall, the best consumables in World of Warships. I bet you haven't really paid that close attention to your consumables before. I certainly only paid them a passing glance, seldom appreciating that there were marked difference in performance. Sometimes this varies between type and others it varies between tier and nation. Let's take a closer look at the breakdown between types, tiers and nations where consumables are concerned. Almost all of this information can be pulled from the in game client in port. Some of the rest of it involved smashing a Campbeltown at close to 40 knots into the side of Battleships and observing what happened. Ah, science!
Engine Boost, Spotter Aircraft & Torpedo Reload Booster
Let's start with the consumables that don't change. These are it. Engine Boost is the same for every destroyer in the game and is (at present) only found on that type of ship. Spotter Aircraft have the same duration and reset timer regardless of ship type. They all provide a flat 20% range boost to the ship that launched them with their primary battery They may have different suvivability by tier but I was unable to pull that information. If you know differently, please let me know. Lastly, Torpedo Acceleration is a bit of an odd duck. Currently, it's only available on two ships: The Hatsuharu and Kagero. It is identical on both ships and, as they are both IJN, it's impossible to tell if it would have different values across other nations. It doesn't vary by tier.
Damage Control Party
This is the first consumable players will encounter, found on their tier 1 cruisers.
When this consumable is activated, it remains active for a set period of time. During this active period, all critical damage is negated. Fires are put out. Floods are plugged up. Knocked out modules such as damaged (but not destroyed) primary batteries, steering gears and engines are restored. The active period for Damage Control Parties is standard for most ship classes except Battleships which vary considerably, with national preferences creating a bias towards some nations. The reset timers are different across most classes. And just when you think it all makes sense, the HMS Warspite breaks the mold entirely.

The next consumable players encounter will be their Smoke Generators and Engine Boosts found on tier 2 Destroyers.
The values of Smoke Generators vary greatly between tiers. Smoke generation is largely taken for granted with few players appreciating how the mechanics work. This leads to a lot of misunderstanding with spotting mechanics. Smoke has three phases. The first is the period when it is being actively emitted. The second phase lasts from the moment the smoke cloud is generated to when it dissipates. The third is the reset timer on the consumable. Note that there is some overlap between these three phases.
The reset timer on all Smoke Generators is universal, regardless of tier, nation or class of vessel laying down the smoke. This is 240s for a standard consumable, 160s for a premium consumable.
Hands down, American (and American derived) ships have the best values for their smoke generators. They not only generate more smoke (with a longer emission period), this also increases as the USN ships climb in tiers. All other destroyers have a static emission period. The amount of time the smoke lasts increases for all nations, with Americans having an enormous lead. One off premium ships tend to follow the IJN & VMF standards unless the ship was derived from an American vessel. The Iwaki Alpha which has its own strange values.

Repair Party is usually encountered at tier 3 for most players (despite the Mikasa having access at tier 2).
Repair Party mechanics deserves it's own thread but I can summarize here. As a ship takes damage, a certain portion of this damage enters a pool which can be recovered through the use of the ship's Repair Party. How much damage enters to pool depends upon the damage's source. This also varies between ship classes. A single charge of a Repair Party restores damage from this pool up to a maximum of 14% of the ship's original, unmodified health (0.5% per second for 28s). So a ship with 50,000 max HP would normally restore up to 7,000hp with a single charge. The Reset timer is universal across all ship types with a 120s / 80s reset timer between standard and the premium consumable.
The damage pool that can be healed for each ship type follows the following pattern:
There are a couple of exception in the game presently. The first is the HMS Warspite -- who's really weird when it comes to her Repair Party. She heals up to 16.8% of her maximum HP pool per charge instead of 14% (0.6% per second for 28s). She also can repair more damage from penetrating hits. Note that contrary to some reports, she cannot heal back more than 10% of citadel damage.
(*) Note for torpedoes, their explosive blast is rather large and the majority of hits striking a ship except at the very extremes may damage the citadel.
The second is the USS Colorado. Rather than the 250.5hp per second (7014hp per charge), she heals back 330hp per second (9240hp per charge). This is a higher raw value than the Warspite (almost 30%) but it doesn't come paired with the ability to create a larger damage pool from which to heal. She conforms to all of the normal Repair Party tropes otherwise. (Special thanks to mrh308 for reminding me!).
This was, famously, one of the first consumables whose difference between nations became common knowledge. This first becomes available to cruisers at tier 4. It can be found at higher tiers on a variety of classes, including the rare destroyer and high tier German Battleships. German Warships gain 2s per tier and increase by a range of 90m per tier for torpedo acquisition and 150m per tier for ship acquisition. For the other nations, their duration remains static until tier 6 where they also gain 2s duration. Their range increase is 150m per tier for torpedoes and 240m per tier for ships. The reset timer is universal across all nations at 3 minutes for the normal consumable, 2 minutes for the premium version.
Hydroacoustic Search active time and acquisition range bonuses, per ship type and tier.
This becomes available for select ships as early as tier 4 with the IJN Yubari, but doesn't become commonplace until tier 6 for most cruisers. In addition, carriers of tier 8 and higher have a long-lasting version with a very long reset. Overall, the Americans really win out with Defensive Fire, getting an extra charge for free. The USN Destroyers also gain access to this consumable at tier 5 and above provided they use their final hull upgrade and swap out their Engine Boost consumable.
The attack and defensive values for Catapult Fighters vary greatly between nations and tiers. The duration and reset timers are standard, however, with a 3 minute / 2 minute waiting time between recovery and launching the next. The active period for all Catapult Fighters is 6 minutes. Note the capacity of the ship varies between classes and types and seems representative of their historic hangar capacity and can vary wildly even between tiers. Note that the Soviet Cruisers do not have access to a Catapult Fighter on any of their ships. In general, the German float plane fighters perform the best at high tiers and the IJN and middle tiers.

The most recent consumable to be added to the game, radar is a highly coveted but largely over-hyped ability. Those that haven't used it regularly believe it to have the ability to level the playing field at the touch of a button. Those that have played with it regularly understand that it is very short ranged and very short lasting, making the demand for this consumable far outstrip its availability. So far, only American and Soviet cruisers have access to Radar, starting at tier 7 with some premiums. In general, the Soviet radar is longer ranged but with a much shorter duration. The American radar increases and range and duration as you ascend the tiers.

So there we have it. The USN comes out with a very impressive list of some of the top performing consumables in the game. Even if we assign draws where values are controversial (such as longer range vs longer duration with radar), the American ships still come out on top. Observe:
