UCS Executor 75457 vs 10221: same ship, fifteen years apart, two opposite price verdicts

This isn't a comparison of two different ships. It's the same one — the Empire's flagship Super Star Destroyer — fifteen years apart, with two retail prices fixed at their respective release dates. No market price, no estimate, no conversion: just what LEGO charged in 2011 and what it charges in 2026 for the same subject.

The comparison, in numbers

Sources: the 10221's Brickset page (3,152 pieces, 5 minifigs, 399.99€, launched September 1, 2011), the 75457's Brickset page and official LEGO Shop product page (6,130 pieces, 749.99€, 7 minifigs, 136cm long), confirmed by LEGO's press release relayed by The Brick Fan ("the longest Star Wars brick-built model to date"). Every ratio in this article is recalculated from these figures, never copied.

Two ways to measure the same ship

By price per piece, the verdict is clear: 0.1269€ in 2011, 0.1224€ in 2026 — 3.6% less. Over fifteen years, LEGO hasn't raised the price of the brick in this segment — it doubled the number of bricks. That's a product change, not inflation.

But the ship didn't grow at the same rate it got denser: 124cm to 136cm, +9.7% in length, for +94.5% more pieces. Density goes from 25.4 to 45.1 pieces per centimeter — +77.3%. And if you divide price by that same length instead of piece count, price per centimeter jumps from 3.23€ to 5.52€ — +71.0%.

Both figures are true at the same time. Price per piece says "cheaper". Price per centimeter says "71% more expensive". This isn't a contradiction in the data — the unit of measurement is what manufactures the conclusion. That's exactly the kind of trap a serious collection tracker should make visible, rather than deciding for you with a single number.

When it actually comes out

Two dates, not one: LEGO Insiders early access starting October 1, 2026, general availability on the LEGO Shop FR October 4, 2026. LEGO's press release says "starting 1 October" — that's the Insiders date, not the public on-sale date. A Darth Vader lightsaber hilt (40897) is offered in October with a 75457 purchase; its exact end window differs between sources and isn't fixed here.

My take

Nowhere do I write that the 10221 "gained value" since its 2014 retirement, nor that the 75457 "will be worth" anything after release — that's not what this article measures, which compares two retail prices at their respective launch dates, not market valuations. What I take away is that the "LEGO is getting too expensive" debate can't be settled with a single ratio. Per piece, LEGO has held its price on this ship for fifteen years. Per centimeter, it charges 71% more for the same act of collecting a flagship model. Both claims are defensible — which is exactly why neither one, alone, tells the whole story.

How I track this with Cault

If I already own the 10221, I don't need to open a spreadsheet to place the 75457 relative to it: Cault shows both spec sheets side by side with their original prices, without me re-entering a single figure. The day I add the 75457 to my wishlist, the price-per-piece and price-per-centimeter comparison stays available instead of depending on a calculation I made once and forgot.

The takeaway

The same ship, fifteen years apart: +94.5% pieces, +87.5% price, −3.6% price per piece, +71.0% price per centimeter. This isn't a ship that gained or lost value — these are two retail prices at two release dates, and a simple lesson: before concluding "more expensive" or "cheaper", check which unit the conclusion rests on.
