In his first appearances, Captain America's shield is an elongated triangle with three peaks at the top:

Now, of course, his shield is round.

When did this change occur, and why?

    When? No idea. Why? Also no idea, though I'd speculate that it was accompanied by a shift in his fighting style; the round shield would allow it to be thrown, just like it is in the MCU, whereas the kite shield would be at best a purely melee weapon, if not entirely for defensive purposes.

  • I know Stan Lee created the round shield.

From Elongated Triangle to Kite-shape shield

I cannot find any in-universe reason as to why this occurred, but out-of-universe I can.

Apparently the original sketch of Captain America came to the attention of Archie Comics (then MLJ Magazines) - they noticed there was a similarity between Captain America's shield and the chest detail of their own character The Shield (below).

The Shield

Consequently, Captain America's shield was changed to the Kite design.

From Kite shape shield to Round shield


The Marvel Wikia site refers to President F D Roosevelt presenting Captain America with this. This puts it between 1933 and 1945

Franklin D Roosevelt presenting Captain America with his new shield

From Captain America Vol 1 255: 'The Living Legend' in which

It details the origin of Captain America and focuses on his early adventures in 1941-42.


As correctly pointed out in the question:

Rogers was originally issued a traditionally "kite" shaped shield made of mundane steel, as well as a sidearm.


This new disc-shaped shield, however, had two main advantages:

1: It was better as an offensive weapon

He discovered:

that its excellent aerodynamic properties made it an effective offensive weapon


2: It was made of a nearly indestructible alloy

Originally, Dr. Myron MacLain was attempting to perfect an indestructible alloy as strong as the legendary 'Adamantine', which Hercules' Golden Mace was made from. Dr. MacLain was hoping the alloy would provide a distinct advantage in the armor of American war machines, during World War II. The Doctor worked tirelessly, using the exotic Vibranium metal and an unknown substance. While the Doctor was asleep, as a result of his exhaustion, an unknown factor caused the metals he was working with to bond.


An almost indestructible shield has obvious advantages over one made from 'mundane steel'!

Not only is the shield nearly indestructible though, it also has other useful properties which are inherent to Wakandan Vibranium, namely the ability to absorb vibratory energies in the vicinity.

The Wiki page on his shield explains the following (however bear in mind that it does not reference the said sources):

Some sources say that Dr. MacLain chose the discus shape because of its versatility, while other say that he used an existing cast designed for tank hatches.

    Re: "Some sources say that Dr. MacLain chose the discus shape because of its versatility, while other say that he used an existing cast designed for tank hatches": Conveniently, these claims are compatible: perhaps he selected the discus shape for versatility, and used the existing cast because it happened to provide the selected shape.

    "able to throw it twice as far" - he was throwing the kite shield around already? Commented Jul 27, 2015 at 13:10

In-universe, Captain America got round shield in 1941. See the middle-right panel of this page from Avengers (1963) #71:

enter image description here

The same panel also shows why Cap wanted to get a round shield.

Note: This comics doesn't give any out-of-universe cue. When the comics came out, Cap already had round shield. In this scene, three Avengers (Black Panther, Yellow jacket and Vision) are in past when Cap didn't know anything about the Avengers.

Out-of-universe, Captain America first appeared with round shield in Captain America comics #2 (Published: April 01, 1941). You can see it on the cover:

enter image description here

The first page:

enter image description here

In the previous issue which was published on March 01, 1941 (whose cover you've included in the question), Captain America kept using that kite/badge shaped shield until the end.

They suddenly changed the design of the shield without giving any in-universe explanation at the time.

  • A side note on the story from Avengers 71; almost ten years later, when Roy Thomas was writing the adventures of Cap, the Human Torch, Namor, et al. during World War II as the super-hero team the Invaders, he retold this story from the viewpoint of the WWII heroes. However, Cap and Namor both resembled their present day selves (round shield, and green scale trunks, respectively). So, the story had to cover why they looked like they did in the Avengers story. Presumably, the shield switch was made in Avengers 71 to make it clear that this was Cap from the past.

Captain America's first shield was badge-shaped. After complaints by a rival comic company that it too closely resembled their hero's symbol, Captain's shield was replaced in Captain America #2 with a disc shaped version.
