The kit was originally released in 1967 as the
USS Franklin (CV–13), and was re-released as the USS Essex (CV-9)
the next year. In 1972 it was rereleased as Intrepid. (CV-11). It was the only class of wartime aircraft carrier available in plastic modeling in or near the 1/700 scale until the advent of the water line Japanese manufacturers in the 1970s. While the flight deck is basically accurate, the hull shape is significantly undersized, and the island suffers from numerous inaccuracies. The kit was greatly surpassed in accuracy by the Hasegawa Essex and Hancock kits in1974, and over 20 years later by a far more accurate series of Essex class carriers by Trumpeter and Dragon.
As a result of these later kits, the Revell Intrepid is not a logical candidate for building as anything other than a toy, as one of these later kits could be accurized far more easily. In fact, it would be significantly simpler to build an Essex class carrier in this scale from scratch than it would be to accurize or kitbash this kit into one.
Nonetheless, the kit is a sentimental favorite of mine, and I recently began contemplating building a "corrected"version of the kit which would have the major errors in shape and detail corrected in a way that is visible. I chose to do this by making all the corrections in white plastic and putty, and leaving the model unpainted so that the revisions are clear. Again, the intent was not to detail or accurize the kit – the kit's armament and other details remain the same – but instead only to correct the kit's inaccuracies using the same level and type of construction of the original model. In other words, I focused on making changes that could have been included in the original kit when it was released.
Date of Model
I chose to model the Intrepid as it appeared at the Battle of Leyte Gulf in October, 1944. I did this for two reasons.
First, the kit lacks a 40 mm quad mount on the front of the island, has multiple 40 mm mounts elsewhere, and the box art and kit painting instructions show a dazzle camouflage pattern. This does not match the Intrepid's appearance as built in 1943, but does match its appearance after a March-June 1944 refit following its torpedoing off Truk in February 1944. Intrepid returned to service with the fast carriers of Task Force 38 in August 1944, so Leyte Gulf two months later was a logical time. This also meant that I could use the extensive detailed (and scaled) plans of the Intrepid in its June 1944 configuration in John Roberts' The aircraft carrier Intrepid Anatomy of the Ship book, reduced to 1/720 scale.
Hull
The biggest change to the kit was obviously going to be deepening the hull significantly. I prepared a profile with the accurate dimensions, which gave me precise calculations for how much additional hull material was going to be needed. I used as my starting point the existing kit's main (hangar) deck, and determined that additional height had to be added in the underwater section of the hull, immediately above the water line, and at the top of the hull just below the flight deck.
Underwater Hull
I decided to replicate the kit's two-part hull, so that I could separate the underwater portion from the rest of the ship in case I ever wanted to paint it and add it to my collection of 1/700 waterline Essex- class models. This meant that the first piece of construction was going to be a separate underwater hull.
Upper Hull
The above-water portion of the hull was built the same way as the underwater hull, with hull sections attached to a longitudinal member glued to the upper water line piece. The approximately quarter-inch section of strip plastic that marked most of the missing depth of the hull above the waterline then served as the guide for how much of the kit's above-water hull would need to be cut away, which was a significant portion below the hangar deck aft, and the entire forecastle forward.
Once the kit's hull sides were securely in place, I added a full hangar deck.
If the insufficient depth of the hull is the worst flaw in the kit, the shaping of the
forecastle is the second. As a result, the hull was completely reframed forward of the #1 elevator, and topped with a new much broader forecastle deck. Again, the hull was filled out with sheet plastic and putty to the correct shape.
The kit's original anchors were cut off the kit's hull pieces and then sanded down as much as possible before being glued on.
Even with the substantial addition below the kit hull, the hull was still slightly too short from the hangar to the flight deck, so another section of sheet plastic was installed between the hull sides and the flight deck raising it to the required level. Interestingly, the hangar openings in the hull were almost completely accurate – so while I had to raise the height of the openings, I didn't have to move them, as I had to do when kitbashing the Hasegawa Essex and Hancock kits. I couldn't help adding some roller doors in a partially lowered position - which I justified because the way the hull pieces are molded, it would have been easy to include this level of detail. 
Hull detailing was deliberately limited, since I did not want to turn this into an accurizing project, but I included the level of detail that was consistent with the molding of the kit's era, including some hull piping which had been lost in all the sanding, as well as supports for the deck-edge elevator. The stern was completely missing the necessary structures, so I included them, built simply enough that they could have been included as part of the kit parts.
Last, the 5 inch gun platforms forward and aft on the port side in the kit completely lacked the necessary sponsons, so I built those up with sheet plastic and putty.
Flight Deck
On the starboard side forward, the Intrepid didn't have the forward 20 mm mount gun tub that some other ships of the class had, so I snipped that gun tub out and replaced it with strip plastic, and added another section a little further back on the starboard side gallery deck. Intrepid did have three small gun tubs near the stern that aren't shown on the kit, so I scratchbuilt those and filled them with matching mounts from another kit. The spares box also provided two more lattice masts aft. The last change to the gallery deck mounts was replacing 5 inch 38 caliber guns in two tubs on the port side aft with 40 mm quads - why they didn't have them in the first place is a mystery.
Island
One of the most prominent errors in the kit's island is the inclusion of an open tube at the front of the flag bridge. It isn't intended to be an AA mount, but instead the gun director that sits on a stalk just in front of and below the flag bridge. I cut it off and installed it on the necessary stalk. I then modified the island platforms to match the Roberts plans, which included both trimming existing platforms, which remain in their original gray, and installing new platforms, including a completely new flag and navigation bridge.
The kit island's worst error is that the tripod mast was molded backwards so that instead of the back legs leaning towards the front, the front leg leans towards the back. I could not fix the kit part, so I scratchbuilt a new tripod mast from rod plastic, and put the kit's mast head platform on top of that. The pole mast on top of the platform is actually the kit mast chopped up. The kit mast is so overscale that I was able to cut it and use the parts for the Intrepid's configuration in the fall of 1944. The yardarms and new mainmast are stretched sprue, but could have been included with t he kit in 1967. The SK and SC radars are sheet plastic, and the SC is mounted on a bracket salvaged from the kit's stack cap.
Influence of the USS Franklin (CV-13)
As noted above, this kit was originally released as the Franklin, and numerous details in the kit match the Franklin far better than the Intrepid.
The Franklin may be noteworthy for one other reason – many of the images of the burning Franklin taken after the attack on March 19, 1945 show her listing heavily to starboard, presenting a profile that is very similar to the shallow–draft Revell model.

Conclusion
All in all, this is the model that I always wanted the Revell Intrepid to be. The only question is whether it'll stay gray and white to show the modifications, will get that hand painted tan flight deck and dark gray patches on the hull that I remember so fondly from almost half a century ago, or will get an accurate camouflage scheme. I still haven't made up my mind about that one.
