[[
Pada Desember 2016, Electron menyelesaikan kualifikasi penerbangan. Peluncuran pertama Electron dilakukan pada 25 Mei 2017, namun roket gagal mencapai orbit karena kegagalan pada peralatan komunikasi di darat. Pada 21 Januari 2018, Electron meluncur untuk kedua kalinya dan berhasil mencapai orbit. Peluncuran tersebut meluncurkan tiga CubeSat menuju orbit.<ref name="nzh20180121">{{Cite news|url=http://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=11979201|title=Blast off!

== Desain ==
Electron menggunakan dua tahap roket yang menggunakan propelan [[RP-1]]/[[Oksigen cair|LOX]] dengan diameter yang sama (1,2 meter). Bagian utama roket dibuat menggunakan material [[Plastik diperkuat-grafit|komposit karbon]] ringan.<ref name="ft_launch">{{Cite news|url=https://www.ft.com/content/41572f8a-fe4d-11e7-9650-9c0ad2d7c5b5|title=Private group in 'world first' cheap rocket launch|work=[[Financial Times]]|last=Smyth|first=Jamie|date=21 January 2018|access-date=22 January 2018}}</ref>

Rocket Lab juga telah mengembangkan tahap ketiga opsional yang dirancang untuk menyempurnakan orbit dari muatan satelitnya. Tahap ketiga ini juga menempatkan satelit ke orbit yang lebih akurat dalam waktu yang lebih singkat. Tahapan roket yang juga disebut sebagai tahapan "kick" ini menggunakan mesin bernama Curie yang dicetak 3D dan mampu melakukan beberapa manuver pembakaran menggunakan [[
Varian tahap ketiga lainnya yang bernama 'Photon' saat ini sedang dikembangkan untuk dapat meluncurkan muatan kecil dengan massa hingga {{Cvt|30|kg}} menuju orbit bulan.<ref>{{Cite news|url=https://arstechnica.com/science/2019/10/rocket-lab-yep-rocket-lab-has-a-plan-to-deliver-satellites-to-the-moon/|title=Rocket Lab—yep, Rocket Lab—has a plan to deliver satellites to the Moon|work=Ars Technica|first=Eric|last=Berger|date=21 October 2019}}</ref>
=== Produksi ===
Pembuatan komponen komposit karbon untuk struktur utama membutuhkan waktu 400 jam apabila dilakukan dengan cara konvensional. Pada akhir 2019, Rocket Lab mengadopsi proses produksi baru menggunakan robot untuk menghasilkan semua bagian komposit Electron hanya dalam 12 jam. Robot itu dinamai "Rosie 'the Robot", terinspirasi oleh karakter dalam serial animasi komedi [[The Jetsons]]. Proses robotik ini dapat membuat semua struktur serat karbon, menangani proses pemotongan, pengeboran, dan pengamplasan hingga semua bagian-bagiannya siap untuk perakitan akhir. Tujuan perusahaan pada November 2019 adalah meningkatkan efisiensi alur produksi Electron hingga mencapai laju produksi hanya tujuh hari untuk satu roket.<ref name="sn20191113">{{Cite news|url=https://spacenews.com/rocket-lab-introduces-robotic-manufacturing-system-to-increase-electron-production/|title=Rocket Lab introduces robotic manufacturing system to increase Electron production|work=[[SpaceNews]]|last=Foust|first=Jeff|date=13 November 2019|access-date=14 November 2019}}</ref><ref name="Forbes-20191121">
Produksi mesin Rutherford menggunakan metode [[Percetakan 3D|manufaktur aditif]] yang telah dilakukan secara ekstensif sejak penerbangan awal Electron. Metode ini memungkinkan kemampuan untuk meningkatkan skala produksi dengan cara yang relatif mudah dengan meningkatkan jumlah dan kemampuan printer 3D.<ref name="sn20191113"
